The Nikon Fisheye Camera was discontinued in September 1961, [28] and Nikon subsequently introduced the first regular production fisheye lens for 35 mm cameras in 1962, [12] the Fisheye-Nikkor 8 mm f /8, [35] which required the reflex mirror on its Nikon F and Nikkormat cameras to be locked up prior to mounting the lens.
(a digital camera with an image sensor which size is similar to 35 mm film in film cameras as the standard film camera format) [2] The vast majority of video and still cameras use lenses that produce nearly rectilinear images. A popular alternative type of lens is a fisheye lens which produces a distinctly curvilinear, wide-angled result.
Leitz Elmarit R19/2.8 ultra wide angle lens for Leica R cameras Ihagee Exa camera with Carl Zeiss Jena Flektogon 1:4 20 mm super wide angle lens. An ultra wide-angle lens is a lens whose focal length is shorter than that of an average wide-angle lens, providing an even wider view. The term denotes a different range of lenses, relative to the ...
Fisheye lenses are wide-angle lenses with heavy barrel distortion and thus exhibit both these phenomena, so objects in the center of the image (if shot from a short distance) are particularly enlarged: even if the barrel distortion is corrected, the resulting image is still from a wide-angle lens, and will still have a wide-angle perspective.
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; [71] that lens served as the "eye" of the HAL 9000 computer from the film 2001: A Space Odyssey, [72] although scenes depicting HAL's point ...
Hemispherical photography, also known as canopy photography, is a technique to estimate solar radiation and characterize plant canopy geometry using photographs taken looking upward through an extreme wide-angle lens or a fisheye lens (Rich 1990). Typically, the viewing angle approaches or equals 180-degrees, such that all sky directions are ...
