Photographic lenses are produced in a variety of types for numerous image formats. Innovations in optical technology enable technically advanced lenses to be produced and camera systems improved. Following descriptions of computer aided design and manufacture and the importance of new optical materials, aspheric surfaces and floating elements, several types of lenses are described in detail, including zoom, soft focus, high resolution, micro, large format and telephoto designs. Also discussed are optical attachments and the optical systems of compact cameras, viewfinders and three‐chip video cameras.
