Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
A zoom lens is a system of camera lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens ( prime lens ). A true zoom lens or optical zoom lens is a type of parfocal lens, one that maintains focus when its focal length changes. [1] Most consumer zoom lenses do not maintain ...
The first widely-available fisheye lens for 35mm cameras was the Fisheye-Nikkor 8 mm f /8 from Nikon, released in 1962, which produced circular images similar to those popularized by the LIFE photographers; that lens served as the "eye" of the HAL 9000 computer from the film 2001: A Space Odyssey, although scenes depicting HAL's point of view ...
Lens mount. A lens mount is an interface – mechanical and often also electrical – between a photographic camera body and a lens. It is a feature of camera systems where the body allows interchangeable lenses, most usually the rangefinder camera, single lens reflex type, single lens mirrorless type or any movie camera of 16 mm or higher gauge.
A telephoto lens, also known as telelens, is a specific type of a long-focus lens used in photography and cinematography, in which the physical length of the lens is shorter than the focal length. [1] : 93 This is achieved by incorporating a special lens group known as a telephoto group that extends the light path to create a long-focus lens in ...
A wide-angle lens is also one that projects a substantially larger image circle than would be typical for a standard design lens of the same focal length. This large image circle enables either large tilt & shift movements with a view camera . By convention, in still photography, the normal lens for a particular format has a focal length ...
Camera. Leica camera (1950s) Hasselblad 500 C/M with Zeiss lens. A camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played ...
Photographic lens design. The design of photographic lenses for use in still or cine cameras is intended to produce a lens that yields the most acceptable rendition of the subject being photographed within a range of constraints that include cost, weight and materials. For many other optical devices such as telescopes, microscopes and ...
