Because the brand on the market card machine, various, this would certainly make category for Digital Camera Battery, especially many of the card machines are overwhelming consumer demand. So, choose from the following several CARDS machine should Angle consideration, let you choose the most suitable card machine.
One, the main problems must be considered
Boot speed and shutter lag: card machines boot speed mainly depends on the lens cap structure. At present the lens is divided into use card machine at type a camera or dive looking type, dive telescopic lens by the lens cap is shot two or monolithic shieldship piece composition. Telescopic lens at least three, one is a type, i.e. out back, and a camera Casio QV-3EX battery. 2 it is lens front have protects the piece, stay out, protect slice camera while open. The third is a special lens cover SLR lens, similar to the lens cap, but in use up more troublesome. Relative to character, the boot looked type lens potential is the fastest speed for paparazzi look very good, but the potential of maximum aperture smaller lens often. Shutter lag depends mainly on the camera's focus speed. Focus speed speed on photography influence, is self-evident.
The camera Casio QV-EX3 battery, focal length and zoom way: card machine lens of brand as long as not inferior brand, its lens camera general difference did not imagination of so serious, therefore can not be simple, that after all CaiSi lens superstition is just a lens authentication. As to choose which lens forms, specific should see their needs, the objective of speak influence are not a. For the focal length, usually we hope the focal length range bigger is better, although large range of great capacity that optical zoom, but this is an error, for example a particular machine, 35-12 times of 425mm from wide Angle optical zoom, to have, just long focal length thousands of yuan, a lot of people think cheap, good value for money. But imagine that in the lens, an SLR machine structure how much money the fixed-focus head? Or "cheap goods is not good" is this truth. That is to say, telephoto doesn't have to be too big, wide Angle or the most practical, best can have 2.8 and even larger aperture. Finally said zoom way, one kind is optical zoom, one kind is digital zoom, digital zoom is using software to realize interpolation method, thus reduced the photo quality, usually don't suggest using, so the camera only digital zoom that equals no zoom function, so we need to pay attention to the ability of optical zoom, card machine by volume restrictions because it is often difficult to have big zoom ability, but from another perspective, all the zoom lens quality basic is three times for the best, so within 3 times of card machine basic optical zoom is common, namely basic to meet general application. Special remind is, some low-end cameras no optical zoom or only digital zoom don't consider buying.
CCD problem: the area of imaging quality CCD has important effect, and that is without question. So, in conditions allow, should choose within the area wants relatively CCD big card machine. If two models are 10 million pixels, a CCD is 1/2.5 inch, one is 1/1.8 inches, that certainly will choose best large area 1/1.8 inches of this. In addition, incidentally card machine of CCD Casio QV3000-PROPACK battery size, currently all the CARDS machine of CCD in inches to indicate the area, but not in distance dimensions as SLR, this main reason or because card machine CCD is too small, that manufacturers can't or can't use length to indicate, there's still an error, which a lot of people would say that card machine labeled inches senseway CCD real size, is actually wrong, actually card machine labeled CCD area, should be the whole of inches total area by a combination of CCD, the diameter of which also includes some CCD stents facilities, popular speaking, the real CCD size is contained in the inches of numerical of.
FangDou function: card machine in small portable at the same time, of a variety of reasons the dithering is inevitable, so now card machine usually will FangDou function as one of important selling point. FangDou function most common has two kinds, a kind of for optical FangDou or call the physical FangDou, a FangDou, also called for digital electronic FangDou or natural FangDou. Optical FangDou is through the lens of physical movement inside machine compensate way to realize FangDou, it is relying on magnetic package, thus effectively overcome suspended lens for camera vibration producing image fuzzy, it through the lens of gyroscope detect tiny within the movement, and 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, thus effectively overcome the resulting image for camera Casio NP-130 Battery vibration of fuzzy, popular, it refers to speak when shooting inside the lens lens can be automatic correct position according to wobble, so as to achieve the purpose of FangDou. Digital FangDou is by raising mode value on and improve the shutter speed to achieve, you're welcome to speak this is deceitful, eventually made a film not empty, but pixels and splash but much. Therefore this is not the true sense FangDou function. So, only to have strong optical FangDou function can be true FangDou camera, this function is very important, and when the choose and buy should key consideration.
ISO mode in particular significance: often, ISO values within the lower, whereas the clear image of imaging quality is poorer, because high mode can reduce exposure time of filming, which caused the jitter photos of compensation fuzzy can play a certain role or prevent, so many vendors will also for one of the selling points, but on the card should be "see little watch big", in fact we took photos, in order to get good imaging quality often hope ISO values as low as possible, after all in the light allow, ISO value set is lower, the image quality is better.Casio NP-L7 battery
Macro function: the so-called card machine should say is micro and macro function actually take function. Namely card with the machine closer shooting close-up, now a lot of manufacturers in the publicity or the evaluation, will only for shooting distance recently 2cm or shorter as highly-touted successes to consumers buy, this is an error. But now that the people there are two different kinds of sounds, a kind of think more short more good, or it doesn't call macro, a expressed as it is good enough, because on the surface since is macro, of course, is the shorter the distance, the better, but if must put the camera casio np-20 battery and was taken to the distance of objects, can shorten 2cm photo get big local features, will they will feel very weird? For example, if in outdoor lighting is very good time, the shooting hua-rui, if put the camera on 2cm or shorter the focal length, if wants to succeed, we must consider the shooting words into looking for metering or the right Angle, but sometimes often because the light blocking the camera, resulting in huge shadow, can not shooting, or want to shoot bees, but haven't put the camera into 2cm, bees had away. Of course, this is not absolute, and finally to see this function's appeal, use this function to shoot something.
LCD screen: from now the development trend of the card machine, basically see will slowly cancel viewfinder, from fuselage optical LCD screen is more and more important role in appear not only the function, composition, browse, change the parameters and even many operation, is inseparable from the screen. There are two important parameters, display a area is a resolution, large area in a visual sense is no shows, here is the key said resolution, attention to the display pixels (here's pixels and photographic components pixel is not the same, especially here, the clarity of the display screen, the greater the pixels should) screen will be more clear, so this parameter is very important. Usually at least 2.5 inches display pixel to reach 15 million above (many had reached more than 20 million) to is fine, of course, with the higher the screen pixel size relative is clearer and more exquisite.
