The lenses attach to the camera using a lens mount, which contains mechanical linkages and often also electrical contacts between the lens and camera body. The lens mount design is an important issue for compatibility between cameras and lenses. There is no universal standard for lens mounts, and each major camera maker typically uses its own ...
However, for the record: the first autofocus lens for a still camera was the Konishiroku Konica Hexanon 38mm f/2.8 [171] built into the Konica C35 AF (1977, Japan) 35mm point-and-shoot; the first autofocus lens for an SLR camera was the unnamed 116mm f/8 [172] built into the Polaroid SX-70 Sonar (1978, USA) instant film SLR; the first ...
Many zoom lenses, particularly in the case of fixed-lens cameras, are actually varifocal lenses, which gives lens designers more flexibility in optical design trade-offs (e.g., focal length range, maximal aperture, size, weight, cost) than parfocal zoom, which is practical because of auto-focus, and because the camera processor can ...
FP. Focal plane. A shutter that opens and closes near to the film or image sensor, usually as a fast-moving slit, as contrasted with a bladed/leaf shutter located near a nodal point of a lens. [12] FPA. Focal plane array. A matrix of sensors positioned in the focal plane of a lens or other focusing device. [12] FPS.
Macro photography. Macro photograph of a common yellow dung fly ( Scathophaga stercoraria) made using a lens at its maximum 1:1 reproduction ratio, and an 18×24mm image sensor, the on-screen display of the photograph results in a greater than life-size image. Headshot of a dragonfly taken with a 100 mm macro lens coupled with a 50 mm lens in ...
Category. : Photographic lenses. A photographic lens or objective is an integrated system comprising one or more simple optical lens elements, which produces an image of a distant object. Wikimedia Commons has media related to Photographic lenses.
210 mm. large format 8 × 10 sheet film. 194 × 245 mm (image area) 312.5 mm. 300 mm. For a 35 mm camera with a diagonal of 43 mm, the most commonly used normal lens is 50 mm, but focal lengths between about 40 and 58 mm are also considered normal. The 50 mm focal length was chosen by Oskar Barnack, the creator of the Leica camera.
Coverage (lens) The coverage of a lens is the size of the image it can produce, measured as the diameter of the image circle produced by the optics. In a camera system the coverage must be large enough to cover the sensor or film used. In a view camera system, because the film plane can be moved independently of the lens plane, the lens must ...
