Recent years, more and more digital camera using a CCD, TTL auto focus mode, further improve the focusing accuracy and make the picture quality improved greatly. In exposure mode, there are shutter priority automatic exposure, aperture priority automatic exposure and manual exposure mode, consumers can choose according to their own hobbies and photograph skills.

Now most of the digital camera uses a built-in zoom lens, and the non-spherical lens is used in the mirror. The aperture gear number increases from 2-3 file to 6 files or so; the lens aperture is also significantly increased. The zoom lens already has a variety of products, and they all greatly increase the flexibility and the imaging quality. Some cameras even with electronic zoom function, which can improve the ultra far shooting ability, especially suit for the wild field scientific persons.
