There are gadgets that now require 12-volt chargers are the reason you need to make sure that you find this type of charger. They are available everywhere, if the stores or online. According to the people who bought its experience, which is not easy to find out. You want a charger, charging high efficiency and effective,consumers are not many. If you ask a user, you know it all and find the wrong product.

 

Fake products are to be so careful on the Internet when it comes to buying a charger for your needs. It can be very difficult to determine chargers and wrong, because the boots are similar in their physical properties.

 

There are chargers, taking their special brand of quality to differentiate their products from counterfeits. It is important to see you in search of that special day, whether you really are buying the best positions on the market.

 

12-volt chargers are easier to find if you know exactly what you want. Want it is best if you read reviews online the first street right before deciding to buy a certain product on the market. Reviews have to take the right path to the 12-volt charger that you need to deal with emergencies.

 

Boots are very important for all devices with batteries. They are very useful, especially in the time when the situation with a view of the battery.

 

The depletion of the battery is possible to recover without the help of porters. To put it to work again, you have to charge a battery that can not find, can restore a dead battery charger, the power to the battery.  so you need to spend time and effort to find the right, will meet your needs. An original chargers value not cheap.so it is important to avoid in the market the cheapest one.

The lithium is a most lightly not- gaseous metal material in the nature, its originally advertise for electric potential to have to be aller low than other any metal, so compared with the battery of other categories, ratio capacity and body density of lithium battery are the all tallest, have incomparable and excellent power.Moreover lithium battery of inside Zu very high, the reason is the electrolyte of its inner part is a gum body but isn't an aqueous solution.In addition, very and lowly containing the electrode material of water rate, physics and chemistry function stability to still make the lithium battery can within the scope of very wide temperature safely work.Separately lithium Canon EOS 50D Battery can under the heat that-55 ℃ low temperature environments and 150 ℃ Celsius degrees work.The sum of lithium battery settles to output electric voltage to 2.7-3.6 Vs.

 

With gather an ethylene lithium battery to compare, the LiMnO2 batteries all have advantage more in the structure strength, body density, safety and exportation ability etc., but it is service life and the half of the former.This kind of battery of inside the Zu compare other Motorola HT750 Battery to all have to be low, therefore be applicable to the equipments of those demand big electric current continuous power supplies very much.

 

The category of lithium battery is a lot of, in common usely have lithium - polyethylene, lithium - mno2, lithium - and sulfur carbonyl chlorides, lithium - sulphur dioxide, and iodinated of lithium battery.The exportation electric voltage that gathers ethylene battery is a 2.8 Vs, its body density is higher.The cylinder form gathers ethylene battery to adopt spiral form cathode, and seal completely by artificial ripples rubber.This kind of structure although it is said firmer, but under the some and special environment, the battery life still has no exhaustion, the rubber seals completely material already aging Be getting more damaged, result in live material's leaking, cause trouble.Iodine's turning the live material of lithium battery is completely solid state, consequently safety had better.This design in the battery inner part has already insulated a layer, when the outer shell is subjected to outside dint impact but breakage, the insulation layer can develop " from more" function.The iodine turns the biggest weakness of lithium battery is inside Zu big, unwell used for a small load of equipments.In the military|the aerospace realm is the most applied of should be LiSO2 batteries.But, the body density of this kind of battery compares LiMnO2 batteries and gathers ethylene battery low, service life and body density only have the half of LiSOC2 batteries.

 

In all lithium batteries, the energy density of LiSOC12 batteries is the tallest, its service life is second to none more and comes to an a year.This kind of battery is specially applicable to those continuous power supply electric currents very small but short time power supply the electric current compare a bigger equipments.Because the life span is long, from turn on electricity small, the this kind of bearing of Casio NP-60 Battery environment ability is also very outstanding.The LiSOC12 batteries more familiar internal structure has 2 kinds:1 kind is spiral to tie up a round type, a kind of is a layer to tie up a round type.On top of that, the PuslesPlus battery adopted compound structure and tied up to round to join compound electric capacity inside the structure in the layer.

 

Actually, the layer ties up the LiSOC12 batteries of rounding the structure, besides which, , other lithium batteries all adopted spiral tie up to round structure.Being spiral to tie up to round structure can raise load ability, but tie up with layer to round structure to compare, its capacity is smaller, from turn on electricity to also more significant.

On April 20, the Casio trade limited company was all new to release underneath EXILIM series touch card of the camera EX-Z3000.BE providing with 16,100,000 cameras, 25 mm wide-angle 800% opticses become the foundation of burnt lens up, the Casio Z3000 still carried the high pure touch LCD screen of a cake of 3.2 inches for the very first time.Hereat at the same time, the Z3000 also has to enjoy high reputation of HDR and HDR art function.Today, this set just released the card machine of returning"emit hot air" to come right away us sky pole the net review to measure room and report for everyone dedicating Casio Z3000 of arriving standing now.

 

What we see is the front side of the Casio Z3000 first, this time arrive at our sky pole the net review to measure room of is the Z3000 of one set powder color.At former Casio Z series digital camera in, the optics becomes burnt all at 500% or 500% following.But the Z3000 carried 800% optics to become burnt lens, but the fuselage thickness only have 22.6 mms.

 

The Casio Z3000 was Casio first set to provide with the card digital camera that the touch holds.The back in fuselage, what we see is a cake of 3.2 inch high pure Dell Axim X50 LCD Screen, the effective pixel attains 460,000:00.Customer's interface makes anyone can pass to smoothly roll over screen menu and click a colorful diagram mark of color to in brief operate each function.

 

Two sides that holds in the touch, we discovered a small detail.Be established two tiny outstanding small rubbers respectively, on the other hand can hold a protective function to the touch, then can be effectively antiskid on the other hand, protect the safety of fuselage.The coping in fuselage, the design here is still very simple and direct.Become the combination of the burnt pole for power pressing button with shutter.But press button in the power of flank, then a design that operates an indicator.

 

The Casio Z3000 is up the foundation provided with to touch to hold in the first time, qualified had strong function at the same time.The HDR technique and art HDR effect that the concentration included to enjoy high reputation, and panorama scanning mode and Casio classic BS pole Zhi mode.We are coming to see the other part of the Casio Z300 design circumstance now.The part in lens, the Casio Z3000 provided with 800% optics to become burnt lens, and still had 1200% super solutions to be like the burnt ability of becoming.We can see from the diagram, the plating of lens film is for the green, article color.The lens being effective plates a film to prevent°fro at take BE, the light is dizzy with the occurrence that the ghost copies a circumstance.

 

In the battery, the Casio Z3000 provided with a piece of model number as NP-110 of 1200 milli- Anne refresh a lithium Casio Exilim EX-Z2000 battery charger.Casio camera the special technical ability technique can carry out the violent battery that refreshes after the completion 560 photographs continuous sail ability once with super big capacity battery.

The biggest mistake area:Pixel more Gao is more good 

The question that is usually a writer to see a lot of net friends need to ask, and is buy a digital camera and then will ask"you see isn't that the machine of 600 all things of the universe vegetables is more better than 300 all things of the universe vegetables?", " Is the digital camera that isn't 800 all things of the universe vegetables very well ah?"Etc..For the purchase mistake area have to point out of BE: 

Pressing to need to be purchased is a right path.With pursue Gao pixel for purchase a principle, buy of not necessarily is a style of good digital camera. 

Some digital camera advertisements enounce that the resolution of the style's product is up to 6,000,000 pixels, but the selling price is opposite and cheap, this temptation toward common consumer the dint Be beyond doubt to is very huge.The manual that cautiously studies the style's camera, not difficult discover so-called 6,000,000 pixel resolutionses however is put to be worth to acquire through a hardware, and physically total pixel however 3,300,000, need not hardware puts the effective exportation pixel of value also however 3,000,000 or so.This is in digital camera and some domestic digital cameras of Fuji express most obviously.The Fuji isn't so bad, putting to be worth later photograph can still keep accepting.But domestic of, for catering to the friend's tastes that know that the blindness pursues a high pixel of some that don't understand a digital cameras, also make to put a value, due to having no core technique putting the effect of value can not accept at all. 

The consumer of differentiation who truely can divide purely to put to be worth a pixel, total pixel, effective pixel on the market returning of today combine not much, certainly want Pou in addition to those consumers who usually make contact with with digital camera.Here mainly meant to don't have to the digital camera over thorough research want to purchase of consumer, some digital cameras producing a company is exactly the weakness that made use of a Sony PSP 3000 LCD Screen consumer, big four promote how the resolution of a certain camera is how high, subsequently induce consumer to buy a debt for it. 

The underneath introduces to correctly purchase a principle for a while: 

Chooses that you purchase a digital camera according to the need of biggest don't  put to be worth a pixel! 

Seeing from the angle that the consumer physically applied, majority of customers used digital cameras to all use to take photo, then carry on figures blunt print.2,000,000~5,000,000 pixel numbers that use widespreadly now can already satisfy a daily need.Among them, 2,000,000 above pixels are the requests that is blunt to print the most basic photograph, 2,000,000 pixels can attain 1600 ×s 1200 resolutions(this is the biggest resolution, suggest to use 1280 ×s 960) and compute according to the standard of general 300 dpis, 2,100,000 pixels can perfectly output the photograph of 5 inches, while 5,000,000 pixels can attain about 2580 ×s 1936 resolutions, can perfectly output the photograph of 14 inches.Stir-fry very hotly on the market currently 8,000,000, can output according to this calculate way 16 inch above photograph.But with heart but theory, you use of arrive?Wash a photograph of 14 inches to need how much !?Say again if the display that shows on the computer 19 inches also shows to 2048*1536, so big photograph you also want to narrow of.Don't say that you buy the digital camera of 800 all things of the universe vegetables, be for narrowing the photograph of 800 all things of the universe vegetables to 300 all things of the universe vegetables to see, if so 500 all things of the universe vegetables are all all right already. 

Similar price, but the pixel differs 1,000,000, what will you choose? 

To 2004 first half year of, make widely available on the market the model appeared 3,000,000 with 400 universal effect pixels keep both of situation, exactly should for these 1,000,000 pixels expend price difference is the affair of different people, different views, however in consideration of 400 all things of the universe vegetables are already the primers that consumes a class digital camera essential direction, and take a resolution more high, take with keep image of the vivid is more big, past the writer tendency choose 4,000,000 products.But the high level model is usually 5,000,000-8,000,000 pixel products, the product like this is suitable to photograph fancier of use.As for the Fuji uses of SuperCCD, consumer while purchasing what to should notice is in fact between taking effect is not likely to own the quality that the together biggest exportation pixel has of etc.(6,000,000 output quality to approach traditional CCD of 400 all things of the universe vegetable effect, never hoping to put value effect can compare with real digital camera of 600 all things of the universe vegetables!).

The second mistake area:CCD and CMOS exposed to light a spare part to don't distinguish the price that CCD and CMOS exposed to light a spare part and become to be like quality to have very big difference 

The present digital camera exposeds to light machine module to mainly have 2 kinds, on being CMOS, the manufacturing cost is low but the picture effect don't calculate too good, another is CCD, the price wants to compare CMOS Gao, but at descend with pixel value be like effect to want good than CMOS.(High level CMOS exposeds to light a spare part, not is consuming a type of digital camera discussion category) 

Moreover, CCD on the market is also divided into 2 kinds currently.A kind of is RGB primary color CCD, a kind of is CYMG to repair color CCD.Both all have a different advantage, if just use a screen and visit fortune-teller a slice, then use primary color CCD of the digital camera should be better, because of general screen is use a color light RGB mode color performance;If the user usually needs to output file into photograph or is engaged in printing exportation, so use repair color CCD is more appropriate.Big parts of primary color CCDs all use SONY currently Super HAD CCD, also have the Fuji exclusively super CCD(SuperCCD), among them super CCD of Fuji with exposeding to light of 45 ° Cape alignment CCD module, therefore feel more on the pixel, but the actual pixel is really not so.Consequently while purchasing the digital camera of Fuji, notice the pixel of actual CCD, don't be cheated by the number. 

Consume a class digital camera, the writer suggests a consumer or purchases to use CCD to exposed to light a spare part of, this realm CCD advantage is very obvious. 

The digital camera of sale mostly used CCD that the Suo Ni company produces on the market currently, like Suo Ni, Canon, and Olympus...etc.;The Panasonic use self product CCD.Majority of products of Fuji are to use self-producting SUPER CCD.Household-use model to say the CCD individual difference is almost delicate, need not demand, the consumer should mainly pay attention to a CCD effective pixel in these three parameters.

The third mistake area:Recognize pure camera in of become burnt function the digital cameras on the market all have optics to become burnt to become with figures now two kinds of burnt functions.The focal distance reflection can take the distance of scenery far near.The digital camera becomes burnt formula BE:Become burnt=the optics become burnt × figures to become burnt.Optics' becoming burnt is to depend on optical lens structure to carry out to become burnt, becoming burnt way and 35 mm camera is just about, the mirror slice that passes to shoot to be like a head scenery that moves to enlarge and narrow to need to be taken, the optics becomes the burnt multiple is more big, can take of scenery more far.(again don't lose the premise of quality bottom)The digital camera of 3,000,000 pixels with 300% optics become burnt is lord, also have 200% or 400%.The figures becomes to burntly enlarge a way is originally CCD a part of pixels of the sensor enlarge the whole appearance, so the effect after enlarging isn't very"true".Some camera marks have Gao to doubly become burnt and purchase or want to make pure its optics become burnt to become each with figures burnt how much, the figures becomes burnt to have no actual meaning, need not lead a high request.Raise an example to explain, the SONY F717 is 500% optics to become burnt*200% numbers become burnt altogether is 1000% become burnt.But F717 only 500% optics become burnt, other depend to handle a chip operation to enlarge! 

Use to take to have the optics becomes burnt digital camera we can regulate to take through a focal distance distance enlarges of scenery, and can own very clear photograph.For currently digital camera and speech, own CCD of same resolution, if 1 style become the burnt camera and 1 style settle burnt(generally only the figures become burnt) camera to compare, they there is also very big difference on the ad valorem space, all generally have to own more than 3 ×s to become to the digital camera of high pixel burnt function, if usually take some distant sceneries or animal, we can also choose 6 × optics to become the digital camera of burnt function, taking appearance like this will be more perfect. 

The size that is limited by CCD, the digital camera usually adopts 1000% in of the optics become burnt lens, part of special product even the adoption own 1200% or so optics to become the lens(currently on the market optics become burnt 12 times of only have the Panasonic Lumix DMC-FZ10 Battery Charger of Panasonic) of burnt ability, and become burnt behind can't result in the obvious influence on image quality. 

What to need to be pointed out BE, much time sale in the factory house will publicizee to own"1000%", "1400%" become burnt ability, this is the optics to become burnt with figures become burnt to multiply each other hereafter get of so-called ability, the figures becomes burnt to have to images quality bigger influence, therefore while purchasing in response to with lens of optical become burnt ability as main reference index sign. 

Now the digital camera of each brand return the lens is to ownly sell a point, such as Suo Ni use"Cai Si standard" lens, Panasonic use the Lai card lens, Canon use self-producting the Canon original factory lens, Nikon use self-producting Ni gram Er lens, Fuji use self-producting Fuji lens dragon etc., at universal type the adoptive lens margin isn't quite obviously in the middle of the digital camera, but purchase at household-use quasi- professional digital camera, the consumer can choose by oneself according to own favour.

The fourth mistake area:Blindly pursuing a shooting of digital camera to be like a current figures product of function to more do is more advanced, the digital camera has already had to shoot to be like function, many consumers also like to purchase the product that can shoot to be like while purchasing figures to be like machine and want to attain one machine two to use, since can use to take photo as well as use to shoot to be like.This kind of viewpoint was exploited by manufacturer and then appeared majority of digital cameras all take now of shooting and being like function, attract the consumer's taste. 

One machine two use a development trend that can say to is a current digital camera product, but the current science and technology level is still not enough with attain perfect two machineses unite as one, many products just come to an a request in this aspect of CCD pixel counting, different model number of the digital camera take of copy elephant quality also different, was wellbad so much, but could not also shoot elephant machine to compare with real figures very much again, so say their to shoot to be like effect to still can not shoot elephant machine with real figures to match.The consumer must understand the taking of digital camera in nowadays of is all shadow elephant of MPEG4 formatses, all is the portrait that depends a per puts together, currently the best digital camera also can carry out 30/second, but portrait can carry out 640*480 levels and shoot elephant machine to basically have no with figures of ratio. 

So the general consumer doesn't want to excessively consider that the digital camera was figures to shoot elephant machine to use.Because even if the manufacturer can't give up a piece of market put together their knot on offer among them.The elephant net E claps the product of type is also, its shoot to be like function is also MPEG4 formatses of, isn't a real film format.

The fifth mistake area:Blindly believe that when the brand effect purchases a digital camera the many people will consider what brand of machine good, recognize later on quasi- product of this brand purchase, but forgets to investigate where does it have difference again well and with other brands product from the same file time.The circumstance that finally may come to one"the famous brand is dishonest to use", the writer usually can hear "buy Suo Ni to have a face, take out to go to very special and spectacular" speech like this.In fact the brand prestige of the digital camera is surely very important, but should carry on overall understand to each manufacturer's product before purchasing to common consumer, see more data, more go to take a shot machine on the scene, attain to know both your opponent and yourself, 100 wars not Dai."Apply is had better"!Buying a digital camera not only for the sake of the face problem. 

The digital camera manufacturer on the local market is quite a few now, the Suo Ni and the Canon, Olympus and Nikon, Kodak and Ke Mei, Fuji and Panasonic, SAMSUNG and etc. product quality is all very quite good, and the function is each has his own strong point.Each manufacturer's products contain his/her own special feature.Needed to choose a rightness according to the oneself model, can for home, trip, work etc. bring endless fun, but blindness of pursue a brand effect isn't practical, a brand doesn't represent it very much all models are good, you say BE? 

Chooses that the digital camera that match oneself's appetite is the most important according to own need of and for example say to need automatic function many, so probably a few machines of Nikon suit you and like to move abundantly and so that the having of Canon is a few to is suitable, the MM chooses a digital camera to probably need an external appearance cleverly made etc., all wants to be according to physically setting out and blindly sees brand disadvantage very big.

The sixth mistake area:Blindly pursue technique parameter 

Some young consumers are interested in new thing and get a fever very much to the new technique.Usually the parameter problem of some digital cameras is endless debatable on the forum.In fact, some parameters are very decisive to consumer, for example the CCD size and optics become burnt multiple etc..But, some parameters to common consumer the meaning isn't very big, for example biggest take a time and adoption what kind of CCD, use what kind of lens, lens motor is what, these numbers consume class digital camera to the main current to say to have no actual meaning, not the elephant uses a single anti- product, some technique the progress is all sign. 

As the home digital camera fancier, must remember these technique parameters to be just the references for purchasing, never spend the excessive energy pursues so-and-so parameter, these time rather investigates more market, understands condition of the market and avoids being calculated by the JS.Because of the function parameter of generally household-use digital camera the difference isn't big, these small technique difference at finally complete of work up is negligible, the influence resulting in to the image is what naked eye can not distinguish, so you since you so don't be "deeply concerned at heart" to some parameters for the sake of the general use, endless debatable:)Wait you buy camera just discover, these functions didn't use up several times, contrary you still want to check for these.

The seventh mistake area:The type of Motorola EX500 Battery Charger corner-battery been forgotten is with continuous sail dint 

The type that uses battery needed to make the understand while being to purchase a digital camera, generally speaking, the digital camera of the use appropriation lithium battery, Nie hydrogen battery not only can save for the user a great deal of money, can also consumedly prolong to take time.The general battery then can not repeat to refresh, the consumer has to continuously purchase just can promise normal use, sky the long day is long, this expenditure absolutely can't be a fraction eyes. 

On the market currently, the digital camera almost uses Nie hydrogen to refresh battery and intelligence lithium battery 2.Nie hydrogen's refreshing a battery advantage is opposite price cheapness, time of use is longer, have more relaxed request to the use environment, if the battery didn't give or get an electric shock to also use on the 5th the alkaline battery replaces, utility.The shortage is the memory effect of battery bigger than intelligence lithium battery, not enough environmental protection, refresh time long.The intelligence lithium battery advantage is to refresh time short, weight the opposite Nie hydrogen refresh battery to come lightly somely, and very environmental protection, almost can neglect to remember an effect.The battery shortage of this kind of type is that the price is more expensive, and permits sex isn't very good. 

The consumer chose a type according to own favour while purchasing, currently circumstance to see, the family uses a suggestion or a Nie the hydrogen refresh battery, total own cost lower, and permit sex like.Request agile consumer to the digital camera to say, the lithium battery is a quite good choice.

The eighth mistake area:Only"Cai Si", "Lai card" is a "profession" lens 

For leaving a profound unfathomable impression for consumer, some give birth to manufacturer to usually enounce that the consumer whom his/her own product used a professional lens, such as, Cai Si, and the Ni section Er, rhenium card, and Shi Nai De...etc., didn't really acquaint with to the camera unavoidably wills believe to think really, be led long a nose by them to walk, until ascended to be still can't realize mistake. 

This kind of phenomenon is in fact many to see, doesn't really understand to the digital camera but thinks that the consumer that carry out digital camera dream quickly usually is familiar"victim" again.We can not say"Cai Si", "Lai card" isn't good, but"Cai Si", "Lai card" isn't always a good lens? 

Is total of come to see, the optical lens of the figures image most famous industry doesn't outside produce a company Carl's•The Cai Si and the Ni section Er, Lai card and Shi Nai De are four, the Cai Si, Lai card is applied to the camera, space of professional realm to begenerally come to be like etc. use, Ni section Er and Shi Nai De then is more applied than professional figures, single anti- etc. realm.The lens adopted all will be beaten refreshing marking, and is explaining that the in the book marks clearly in detail, consumer's going to Internet to ascend a search can also easily check for a while. 

For example say that SONY and PANASONIC all generally say that what oneself uses is "Cai Si", "Lai card" lens, in fact everyone doesn't want excessively superstition.Because these lenses is also "Cai Si", "Lai card" to authorize they produce of, not necessarily truely come from original factory.

The ninth mistake area:Buying the digital camera will be one-step and good enough 

First make know own fixed position, connect down consume convenience many.The you as a consumers want to consider first what the fixed position that purchase a digital camera to you is, budget how much, avoids investment waste and again invests.The thought of "the one step is good enough" isn't very commendable. 

Generally press the price to divide:Below 2500 dollars is a household-use primer universal type, 2500 dollars~4000 dollars is household-use essential type, 4000 dollars~6000 dollars is household-use quasi- professional, above 6000 dollars belongs to a domestic expenses fever class.If you to price not sensitive but have much of to pursue to the function, can directly consider the product of above 6000 dollars;If you don't have too many budgets and want to experience personally figures to photograph the fun for bringing to suggest to purchase the digital camera of below 2500 dollars, it completely can satisfy you to catch a daily life fascinating demand;If you are a more overly critical person, don't want to invest too many want to own better function again to practice to photograph a technique, that can Zheng big eyes look for so-called Gao Xing Jia compare digital camera. 

A lot of consumers reflect how to have no a 800 all things of the universe vegetables of and become to be like quality okay, the external appearance is professional, low-cost digital camera.This is just a kind of viewpoint, be you truely want to buy of time, never purchase with such an one-step good enough viewpoint, if don't exaggerate so of say, you were to can not buy a digital camera.

The tenth mistake area:Quality with then hold of balance 

Proceed from the reason on the technique development, at least currently come to see this 2:00 or don't can make to arrive very very equilibrium.Become a direct proportion with the whole machine physical volume on function of universal meaning, the general shape vogue then holds of the digital cameras can't own very outstanding function, function many but whole digital cameras only the fuselage general weights all will be above in the 400 g, to common domestic expenses since want to consider outstanding quality again want in consideration of take of it can not become the nuisance that you leisurely play to play. 

The MM wants that buying camera features is cleverly made very important, so the mental state will have preparation, the quality of appearance is impossibly very good. 

Want to make a profession point need not wanted to put into own pocket of digital cameras. 

The possibility that both have both is too small, come to speak currently that the good elephant hasn't appeared. 

The 11th mistake area:Is Japanese the native machine quality compare domestic construction machine good 

A lot of consumers all exist very big mental shadow on this problem, all feel that the day produces a digital camera just on the whole of the top is a positive original factory article.In fact now mostly manufacturer for declining low cost all set up factory in the domestic, for example Suo in Shanghai is wide, Suzhou Fuji, Dongguan widely unite an etc. and regardless carry on a spare parts construction to still keep carrying on originality production and all always and strictly carry through this brand unifies of quality policy, and will carry on a strict sampling test before flowing into market, it is few to exist the circumstance of individual difference, therefore don't form thinking settle power, the quality in front goes, the habitat is of no account.However, according to my understand, several years of native Japanese manufacturer early really has the circumstance to make the different grade product selling into different place respectively.Certainly, it is basic to have already had no problem like this now. 

Also need to remind a consumer, while buying a digital camera currently a lot of JSs for attracting your the purchasing mental state produces for your recommendation day on your own initiative of digital camera, at this time you want very careful, because a lot of digital cameras only what mainland produce is a positive article, just have a whole country allied protect, this must be careful, never the superstition produce day very well.

The 12th mistake area:"Tasting is fresh" is with the mistake mental state of "again etc." 

A lot of consumers all have 2 kinds of tendencies in purchasing time, 1 kind is to release to the new machine of some brand that has been paying attention to, just became available in the market right away buying;Another is a wait again etc., expect that the digital camera that oneself likes is expecting that the price inside time declines the mental bottom line that can bear into he or she's budget. 

Said for this 2 problem writers his/her own suggestion: 

The publicity of the new product affirms a lot, some consumers forbid not to live temptation buying, not only affirm to reduce price after a month, and the new machine didn't bear the examination of market, probably some bugs have no disheveled hair now, cause bad result.Here writer inconvenience the roll call speak the problem of so-and-so brand, but some memory card mistakes make the digital camera recruited the affair of time have already taken place. 

Generally speaking the new product digital camera becomes available in the market the current price space Be by all means hard to accept, majority of consumers all hold currency to hesitate, at become available in the market a month future reunion carry on reducing price to publicizee for the first time, at become available in the market 3 month future reunions carry on reducing price to promote sales to open a market for the second time, becoming available in the market 6 around months will carry on to reduce price to rob to have quota in the market for the third time, at carry on reduce price for the third time after mean that this digital camera gets into mature expect, at this time price also gradual steady, led half year again probably to also stop production quickly, a style of life cycle of digital camera can't longer than 2 years, is also say all generally will stop production in 2 years. 

Therefore consumer while purchasing should at become available in the market to take down in 6 around months more worthwhile, digital camera like this since not seem to be dated price also calculate justice, certainly reduce price of range because of brand but difference.

The 13th mistake area:Is saving to lie quality-prescribe medicine for specific ailment usually have Memory that the CF card, SM card, SD card, the memory stick of Suo Ni and Suo Ni lately expand Stick Pro, among them, the CF card is most extensively the cheapest, use;The SM card is just and gradually replaced by the CF card to release a market now;The memory stick of Suo Ni and Memory Stick the Pro price is the tallest, and can be used for the Suo Ni series digital camera and limit sex very big, purchasing the consumer of the Suo Ni series digital camera has to compare consumer who choose other brand digital cameras at saving lie quality tops to expend more silver;The advantage of biggest SD card is that the physical volume is small, and permits sex strong can be the MP3 players and cellular phones of saving lie quality, for pushed forward the vogue model of small physical volume to do to contribute.In addition, Fuji and Olympus company united to develop minimum XD card inside the industry, however the card's price is expensive, the prospect is still not clear and distinct(everyone is to say so, but writer currently circumstance to say, feel that the pricing margin has been very small, a SD card of 128 Ms is 150 dollars, and XD card is also 260 or 270),the advantage of speed is still more obvious.At the same time upper part cent brand in market digital camera can and permit two among the memory cards, canning immediately use CF card can also use SM card the product like this has a very superior enlargement and also needs to be noticed while purchasing. 

Saving of different brand lies quality the difference physically isn't very big on the Nikon MH-65 Battery speed, this didn't need to be demanded, but still kept suggesting to purchase the public praise better big factory product, CF and CFII card to still keep choosing SANDISK, the gold private's wait big factory of of a good many, and SD card felling Panasonic, Toshiba contain very strong real strenght, the XD in fact only has a Fuji production manufacturing, the Olympus is in fact also a Fuji labor of.

he 14th mistake area:Choosing digital camera service don't definitely forget 

Serve:Serve, sell in the service, after-sales service before selling. 

These when you want to purchase a digital camera, did you consider into?You choose of digital camera in addition to consider parameter, external appearance and become to be like enough?You have already thoughted of if machine how to handle wrong manufacturer?This is easily be neglected, is also permit a mistakable problem.Make widely available day by day along with the digital camera, the seriousness of problem has already undoubtedly exposed. 

Correspond of report in the IT168 have already appeared a lot of times, associate, Suo Ni, Panasonic and Canon.All or many or little emergence interfere with, all of these are the problem in service category, hope to never neglect when you purchase a digital camera.Must enough value. 

Can only provide a satisfaction of, superior quality of the manufacturer of service is the manufacturer who has a long-term development plan, be worth trust of manufacturer.

The digital camera market now very heated up,attracts many consumers,everybody in succession,network,etc.Through the newspaper about the digital camera means information.They care most is main or price,the price of general computer stores than urban commercial center emporium cheaper price many,even and gome,suning such comprehensive appliances stores,or have compared price advantage.

 

But for digital camera performance,understand,after all many consumers who rarely before,although with no digital camera is evolved from traditional camera,but judging from the imaging principle,the gap is still large and some such as optical zoom,digital zoom,effectively pixels,interpolation,and other special terms,for their part,both strange and familiar because almost all,familiar with the digital camera will have these parameter annotation,and strange because consumers of these parameters are not understanding.Then,the Nikon MH-18 Battery Charger term of a digital camera is introduce,one alphabet popularity.

 

Optical zoom

The optical zoom is digital camera is one of the most important characteristics,such as panasonic's FZ series,konica minolta Z series are big optical zoom and famous.Learn zoom lens is through mobile lens to change within the key position of the focal length of the lens,change the length of days,and change the lens size,so as to realize the image perspective the amplification and narrow.

 

In order to let the traditional photographers easily understand consumption level of digital cameras the meaning of the focal length of the lens,we often converts it into 35mm camera (film cameras),and the equivalent focal length focal length of the lens refers to parallel light pass through the lens,the focus of the collection of the distance between to lens.If be taken object positioning unchanged,the focal length of the object lens magnification can present direct relationship,if want me to use a word to describe optical zoom word,that is "telescope".

 

Big optical zoom type digital camera generally have about 10 times more with the optical zoom,FangDou function,can clear shooting to 25-30 metres thing,and a light thin card at the dive machine because of the lens design,also has 3 times optical zoom,usually within 10 meters of the panoramic view of objects can be on the market.At present main or to 3-4 times optical zoom digital camera.If people to oneself mainly use digital camera optical zoom is not satisfied,you can choose to buy a barlow in improving visible distance,such as buying a * 1.5's barlow,then a 3 times optical zoom digital camera by 3 times the maximum zoom multiples 4.5 times.But I'm a personal doesn't suggest that we purchase additional lens,way is relatively large,secondly to invest a bigger influence quality.

In addition,it will be about wide-angle mention,because the big wide Angle of digital cameras are popular with the customers to win many families,usually less than in the focal length of rounded on the machine performance wide-angle are quite good,but consumers should pay attention,because the big wide Angle is distortion of all picture will certainly have an impact,advice before buying can go to a professional network or photography look at the community the wide-angle photo.

 

Digital zoom

Although digital zoom and optical zoom just two words,but the difference is very big difference,it is through digital camera in the picture of the processor,in every pixel area increases,so as to achieve the purpose,just like we enlarge in ACDSEE image processing software,such as the pixel image forced gap,but this process in a digital camera,transform the CCD photographic element using Nokia N71 LCD Screen part of the interpolation method to amplify pixels.And optical zoom is different,digital zoom is vertical upward in a light-sensitive devices change,but give a person with zoom effect.Because the whole process without any change,so focus image quality is increased with the amplification proportion,gradually decreases.

 

Optical FangDou

As optical FangDou technology,and not let bodies not dithering,it is relying on special lens or CCD photographic components in the structure of maximum reduce operator in use process because of dithering images is not stable.Caused through the lens FangDou is mainly by Canon of realization,they represented with nikon lenses on magnetic parcel suspension,thus effectively overcome the images produced by camera vibration fuzzy,this for big zoom lens digital camera can provide the same effect more apparent.

 

Usually,lens detected within the gyroscope moves,and tiny will signal to the microprocessor immediately the displacement calculated to be compensated,and then through compensation lens groups,according to the lens dithering direction and compensate the displacement,effectively overcome the vibration by camera.And the resulting image by fuzzy FangDou,currently in realizing the CCD only konica minolta can do that and it's principle and Canon,panasonic optical prevent jitter technology instead,depend on CCD floating achieve the purpose of FangDou.Principle is fixed in a first will CCD can move around on the stent up through the direction of gyroscope induction camera shake and amplitude,and then sent to these data to the sensor,amplification,screening processor calculated can offset the CCD travelmotion of FangDou function.Optical effect is quite obvious,in the ordinary circumstances,open this function can improve 2-3 files to shutter speed,hand-held shooting won't produce vague phenomenon,for beginners,the effect is very apparent in the telephoto type digital camera,the effect also is almost immediate.

 

Electronic FangDou

Electronic FangDou,which is based on CCD image on analysis,then use edge image compensate,like optical zoom and digital zoom is same,it just for the collected data post-processing,should do someting,and no practical effect,instead,for the destruction of a certain degree definition.Consumers in a choice,pursue FangDou function words,must see clear exactly is optics,or electronic,if is electronic,you can consider to give up.

 

CCD photographic components

CCD sensor and that charge couplers,it is a special kind of semiconductor materials,by a large number of independent photosensitive diode composition,according to the matrix form commonly alignment.

 

At present,there are many kinds of CCD,including surface is mainly applied in formation CCD digital camera.It is composed by many single photosensitive diode array of positively square,the whole like these photographic diode as laying bricks array to form can output must resolution image of CCD sensor.From the function for Motorola MTS2000 Two way Radio Battery,CCD photographic components in some degree of equivalent to traditional camera film.From the consumers' point of view,the CCD photographic components of course is the bigger the better.

 

believe a lot of consumer goods in the brand saw a noun COMS,actually it is also a kind of photosensitive components,only on cost significantly less than CCD,in power consumption,but also less than CCD in pixels control and imaging quality aspects as CCD (here only refers to the size of smaller CMOS photosensitive components),so only in low-end digital cameras and cameras design commonly used.

 

In addition,about SuperCCD,it is a CCD Fuji original with regular CCD technology,it is the biggest difference lies in that it has changed the matrix CCD four unbleached some synthetic a pixel,the BaBianXing geometry structure and the principle of continuous arrangement,make honeycomb photographic unit can make better use of the CCD surface space,in pixels under the condition of equal acquired more information.

 

effective means of real photographic imaging in pixel values.The highest pixel values are light-sensitive device of real pixels,this data usually contain photosensitive device of nonimaging part,and effective pixel is in lens zoom range of value under.Pictures out conversion of general stored in pixels,each pixel is digital picture of the smallest unit of area.

 

The area of the pixels,the picture.In the pixel area under the condition of invariable,digital cameras can gain the maximum image pixels,namely for effective pixel.Users in the purchase digital cameras,should pay attention to see digital camera pixel is how much,because pixel values is the key decision picture quality.

 

interpolation

Interpolation is formed by CCD photographic components to the actual XiangSuShu,using specific software to a certain degree of fuzzy processing in space,after filling out between,thereby increasing image pixels.

 

It is not generated by CCD directly,just through program constantly generated a magnifying calculated image after image though,amplification,clean surface look more smooth,we see from the surface,total pixel parameters exaltation really,but CCD generated actual pixel values in the whole process without change.But such "improve" the quality of the image itself will affect local amplification,after you will find,many details,will lose,it and we said before optical zoom and digital zoom truth.

 

Shutter speed

The shutter usually divided into electronic shutter and mechanical shutter,but in consumption level of digital cameras,basic use is electronic shutter,it is to control the length of exposure time the film a mechanical or electronic device,usually shutter device is designed on the fuselage or lens.Filming movement within objects if shutter release time is too long,sports object in different parts of the CCD photographic elements had taken out of the imaging result may not clear pictures,and when the shutter speed quickly,sports object in CCD photographic elements imaging haven't obvious move and exposure process has been completed,effect is clearer pictures,such as sports objects in the picture.Frozen

 

Usually,control the main is exposure camera aperture size and shutter speed,of course,and the size of the mode of ISO also has certain contact.Home users choose camera usually don't need what to shutter speed requirements.

 

aperture

The aperture is a used to control the light through the lens face,enter a bellows inside the amount of light in the photographic equipment,it is usually on the lens,the F value internal express size.Usually the smaller aperture F value at the same time unit,and the amount of light more into,instead,aperture,the greater the F values at the same time unit into amount of light and too little.

 

In actual use,aperture and shutter speed has a very direct relation about depth of field.,actually and aperture are directly related,had used SLRS consumers must know,caliber,it is difficult to produce small lens narrow depth of field,so to try every possible realizing foreground vague effect,usually adopts maximum aperture + maximum focal length or open macro mode.

 

SLR

SLR Digital camera refers to the Single Lens reflective Digital camera,namely,Digital Digital camera performance alone,Lens Reflex reflectors,the abbreviation of DSLR.Working principle:

 

In the SLR digital camera work system,light rays through the lens,reflection to arrive after reflector screen and the focus on video,JieMuJing and formed through five prism,we can see the viewing window scenery outside.By contrast,general digital camera can only through the LCD or EVF see the images.Obviously directly see images of the image than by dealing with see more advantageous to the shooting.

 

When shooting,when in DSLR shutter button press will upgrade,reflector,CMOS curtain will also open,through the lens of light and onto the original photographic,then the photographic must immediately after restoration,viewing window again can see images.Single lens reflective camera this construct determined it was fully,shot through the lens autofocus,it can make viewing window we could see in the video and film is always the same,its point range and actual shooting range basically consistent,very beneficial to 3.0-inch intuitively composition.

 

Main features:

One of the great SLR digital camera that can exchange the characteristics of different specifications of lens,this is SLRS natural advantages,it is not normal digital camera.

 

In addition,now SLR digital cameras are located in the high-end product digital camera,therefore in the quality of relationships digital camera photography photographic components (CCD or CMOS) of area,the area of digital SLR than ordinary digital camera,this makes the SLR digital camera each pixel's light-sensing surface area are far larger than normal digital camera,so each pixel also can show more meticulous brightness and color range,make digital camera's photography SLR general digital camera quality significantly higher.
