Digital cameras with wide-angle lens and camera, as the main purpose is to expand the shooting range. For example, in a small space or small room, with wide-angle lens to the lens can not solve the ordinary footage.
Digital cameras with wide-angle lens, a strict should be called "Wide-Angle Lens," because the so-called "Lens" attached to the original only in the lens. Different digital cameras to attach a different angle lens, such as home digital video camera lens diameter 37 mm, 43 mm, etc., professional <digital camera lens with 52,58,72 mm and so on. Wide-Angle Lens models the manufacturers are not the same identity, such as Panasonic's 4307, that can be attached to the 43 mm digital camera lens, the wide-angle multiple of 0.7 times the original lens that can shoot the scene 70% smaller , equivalent to the original lens range 1.43-fold. Sony and Panasonic is different from its wide-angle lens attached logo and Panasonic just turn, such as 0637 table 0.6 of its wide-angle multiple times, can be attached to 37 mm lens on a digital camera to use.
Using wide-angle lens attached, although you can expand the shooting range, but there are some image quality loss. Such as digital cameras with wide-angle lens attached, the four corners of the screen will be a slight blurring, if wide-angle lens without hood, very prone to faint light, like Sony's 0637 consumer-grade wide-angle lens is simply no additional installation hood of the interface, so, if not very need, the use of wide-angle lens attached should be cautious.
