Two years earlier, the lens had been introduced as a one-touch zoom in the manual-focus Minolta SR mount (as a "plain" MD lens). However, production slowed and then eventually stopped for both the AF and MD versions; its successors, the 70-210mm f / 3.5-4.5 and 70-210mm f / 4.5-5.6 had none of the qualities of the original and build and image ...
A body-cap lens is an extreme type of pancake lens that is designed to both protect the camera internals as a body cap normally would, yet still allow the user to take photos. These lenses are manual focus only and generally have no more than a couple of optical lens elements, no image correcting elements, a very-slow fixed aperture, an ...
Three of Minolta's Rokkor brand of lenses were made specially for the CLE: the M-Rokkor 28 mm f / 2.8 wide-angle, the M-Rokkor (-QF) 40 mm f / 2 standard, and the M-Rokkor 90 mm f / 4 telephoto. The earlier Leica CL 40 mm and 90 mm lenses had single coatings , and later Minolta CL-E versions of these two lenses, plus a 28 mm, were multi-coated ...
HCD lenses are optimized for slightly smaller image sensors covering 48×36 mm (1.9×1.4 in), [95] so the crop factor for HCD lenses is slightly greater at 0.72. With these sensors, an 80 mm lens would have the equivalent coverage of a lens with a focal length of approximately 60 mm on a "full-frame" camera.
Schematic of a conventional and a periscope zoom lens A smartphone with a 5x optical zoom periscope lens camera, recognizable by the rectangular shape of its lens. A periscope lens, sometimes called a folded lens, is a mechanical assembly of lens elements that uses a prism or mirror to redirect the light through the lenses with a 90° angle to the optical axis, as in a periscope.
Lens attached to camera as used for Kubrick's Barry Lyndon. The Carl Zeiss Planar 50mm f /0.7 is one of the largest relative aperture lenses in the history of photography. [1] The lens was designed and made specifically for the NASA Apollo lunar program to capture the far side of the Moon in 1966. [2] [3] [better source needed] [4]
The first lens to carry the Rokkor designation was a 200mm f / 4.5 lens that came with the hand-holdable aerial camera Chiyoda SK-100 in 1940. [1] After the Rokkor name was dropped and no longer engraved in new lenses after 1980/1981, [1] the Rokkor name resurfaced two times.
The Zeiss Hologon is an ultra wide-angle f=15mm f / 8 triplet lens, providing a 110° angle of view for 35mm format cameras. The Hologon was originally fitted to a dedicated camera, the Zeiss Ikon Contarex Hologon in the late 1960s; as sales of that camera were poor and the Zeiss Ikon company itself was going bankrupt, an additional 225 lenses were made in Leica M mount and released for sale ...
