For a camera, the lens is the eye. It collects the light rays reflected to it from the scene being photographed, to create an image of this scene on the film or camera sensor. Thus, there is no way to obtain a good image, whether still or motion, wit

A Fresnel lens is an optical device that approximates the performance of a conventional bulk lens while using far less lens material for both cost and space effectiveness. However, the use of current solid-type materials fixes the lens optical perfor

Compact system cameras (CSCs) are commonly used nowadays and feature enhanced video functions and thin yet light interchangeable lenses. They differ from digital single-lens reflex (DSLR) cameras in their lack of mirror boxes. CSCs, however, have aut
