A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens. Instead of producing images with straight lines of perspective, fisheye lenses use a special mapping, which gives images a characteristic convex non-rectilinear appearance.
Nikon Corporation is an optics and photographic equipment manufacturer headquartered in Tokyo, Japan. The companies held by Nikon form the Nikon Group.
Sigma Corporation is a Japanese company, manufacturing cameras, lenses, flashes and other photographic accessories. All Sigma products are produced in the company's own Aizu factory in Bandai, Fukushima, Japan. Although Sigma produces several camera models, the company is best known for producing high-quality lenses and other accessories that are compatible with the cameras produced by other companies.
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. Lens mounts are also used to connect optical components in instrumentation that may not involve a camera, such as the modular components used in optical laboratory prototyping which join via C-mount or T-mount elements.
The Nikon F3 was Nikon's third professional single-lens reflex camera body, preceded by the F and F2. Introduced in March 1980, it had manual and semi-automatic exposure control whereby the camera would select the correct shutter speed. The Nikon F3 series cameras had the most model variations of any Nikon F camera. It was also the first of numerous Nikon F-series cameras to be styled by Italian designer Giorgetto Giugiaro, and to include a red stripe on the handgrip – a feature that would later become a signature feature of many Nikon cameras.
Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 30.15 mm field diameter. It is therefore also equivalent in size to the Super 35 motion picture film format, which has the dimensions of 24.89 mm × 18.66 mm and Ø 31.11 mm field diameter.
The Nikon F-mount is a type of interchangeable lens mount developed by Nikon for its 35mm format single-lens reflex cameras. The F-mount was first introduced on the Nikon F camera in 1959, and features a three-lug bayonet mount with a 44 mm throat and a flange to focal plane distance of 46.5 mm. The company continues, with the 2020 D6 model, to use variations of the same lens mount specification for its film and digital SLR cameras.
The Nikon FM10 is a manual focus 35 mm film camera formerly sold by Nikon Corporation. It is of SLR design and was first available in 1995. It is normally sold in a kit that includes a Zoom Nikkor 35–70 mm f/3.5-4.8 zoom lens, although a Zoom Nikkor 70–210 mm f/4.5-5.6 zoom lens is also available. An electronic companion model known as the FE10 was also sold at one stage.
Nikonos is the brand name of a series of 35mm format cameras specifically designed for underwater photography launched by Nikon in 1963. The early Nikonos cameras were improvements of the Calypso camera, which was an original design by Jacques-Yves Cousteau and Belgian engineer Jean de Wouters. It was produced in France by La Spirotechnique until the design was acquired by Nikon to become the Nikonos. The Nikonos system was immensely popular with both amateur and professional underwater photographers. Its compact design, ease of use, and excellent optical quality set the standard for several decades of underwater imaging. Nikon ceased development and manufacture of new Nikonos cameras in 2001, but the camera remains popular, and there is a large and active secondary market.
The Leica R bayonet mount is a camera lens mount system introduced by Leitz in 1964. The R mount is the standard method of connecting a lens to the Leica R series of 35 mm single-lens reflex cameras. The mount is descended from those used for the Leicaflex, Leicaflex SL and Leicaflex SL2 SLR cameras, but differs in the cams used to communicate lens aperture information to the camera. 3 cam lenses are compatible with all of the Leica SLR cameras, while R-only lenses have a slightly different mount shape that will not fit on the earlier cameras.
This article details lensesfor single-lens reflex and digital single-lens reflex cameras. The emphasis is on modern lenses for 35 mm film SLRs and for "full-frame" DSLRs with sensor sizes less than or equal to 35 mm.
The Nikon NASA F4 Electronic Still Camera is one of the first and rarest fully digital cameras with development started in 1987. While Nikon delivered a modified Nikon F4 body, most of the electronics for the digital camera and housings were designed and manufactured by NASA at the Johnson Space Center and other suppliers. It was first flown in September 1991 on board the Space Shuttle Discovery, mission STS-48. Later the cameras were flown on several other Shuttle missions including STS-44, 45, 42, 49, 53, 56 and 61.
The 18-55mm f/3.5-5.6G AF-S Zoom-Nikkor lens is a midrange zoom lens manufactured by Nikon for use on Nikon DX format digital SLR cameras. Often included as a kit lens on entry-level DSLRs, it also can be purchased separately from the camera body. Nikon first introduced the lens in 2005 and has provided three subsequent updates. Following are the four variants as of 2014:
The Nikon S-mount is a type of interchangeable lens mount used by a series of Nikon 35mm rangefinder cameras. The lenses were sold under the name Nikkor.
The Nikon F-mount teleconverters are a group of magnifying lenses mounted between the lens and camera bodies using the Nikon F-mount. Currently, 1.4x, 1.7x and 2x converters are available separately; a fourth, the 1.25x, is available only with Nikon's newest 800mm supertelephoto lens.
A mirrorless camera is a digital camera which, in contrast to DSLRs, does not use a mirror in order to ensure that the image presented to the photographer through the viewfinder is identical to that taken by the camera. They have come to replace DSLRs, which have historically dominated interchangeable lens cameras. Other terms include electronic viewfinder interchangeable lens (EVIL) cameras and compact system cameras (CSCs).
The Nikon 1 series is a discontinued camera line from Nikon, originally announced on 21 September 2011. The cameras utilized Nikon 1-mount lenses, and featured 1" CX format sensors.
The Nikon D5600 is a 24.2 megapixel upper-entry level, APS-C sensor DSLR announced by Nikon on November 10, 2016, as the successor of the D5500. The camera has an F-mount.
Nikon Z-mount is an interchangeable lens mount developed by Nikon for its mirrorless digital cameras. In late 2018, Nikon released two cameras that use this mount, the full-frame Nikon Z7 and Nikon Z6. In late 2019 Nikon announced their first Z-mount camera with an APS-C sensor, the Nikon Z50. In July 2020 the entry-level full-frame Z5 was introduced. In October 2020, Nikon announced the Nikon Z6II and Nikon Z7II, which succeed the Z6 and Z7, respectively. The APS-C lineup was expanded in July 2021, with the introduction of the retro styled Nikon Zfc, and in October 2021, Nikon unveiled the Nikon Z9, which effectively succeeds the brand's flagship D6 DSLR. The APS-C lineup was further expanded with the Nikon Z30, announced at the end of June 2022. The Nikon Z6III was announced in June 2024.
