The Fish-Eye Rokkor 16mm f/2.8 is a prime fisheye lens produced by Minolta for Minolta SR-mount single lens reflex cameras, introduced in 1969 to replace an earlier fisheye lens, the UW Rokkor 18mm f/9.5. It is a full-frame fisheye lens with a 180° viewing angle across the diagonal.
A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. [4][5]: 145 Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens. Instead of producing images with straight lines of perspective (rectilinear images), fisheye lenses use ...
The Micro Four Thirds system (MFT or M4/3 or M43) (マイクロフォーサーズシステム, Maikuro Fō Sāzu Shisutemu) is a standard released by Olympus Imaging Corporation and Panasonic in 2008, [1] for the design and development of mirrorless interchangeable lens digital cameras, camcorders and lenses. [2] Camera bodies are available ...
Examples of body-cap lenses include the Olympus 9mm F8 Fisheye and Olympus 15mm F8 for Micro Four Thirds and the Fujifilm XM-FL 24mm F8 for Fujifilm X-mount. [2] [3] Panasonic released a manual-focus lens for the L-Mount that is nearly the size of a body cap, but it does not have a retractable lens cover: the Lumix S 26mm F8.

Fisheye lens; first 600 units used a different barrel construction internally; [17] optically similar to the Minolta MC Fish-Eye Rokkor 16mm f / 2.8 (a.k.a. Leica Fisheye-Elmarit-R 16mm f / 2.8) produced up to 1981 with an optical design originally introduced in 1966/1968. Minolta AF Fish-Eye 16mm f / 2.8 (later revision) 2578-110, 2578-610 [19 ...
Lenses with focal lengths of 8 to 16 mm may be either rectilinear or fisheye designs. Wide-angle lenses come in both fixed-focal-length and zoom varieties. For 35 mm cameras, lenses producing rectilinear images can be found at focal lengths as short as 8 mm, including zoom lenses with ranges of 2:1 that begin at 12 mm.
A Luneburg lens (original German Lüneburg lens) is a spherically symmetric gradient-index lens. A typical Luneburg lens's refractive index n decreases radially from the center to the outer surface. They can be made for use with electromagnetic radiation from visible light to radio waves. For certain index profiles, the lens will form perfect ...
