Fujinon is a brand of optical lenses made by Fuji Photo Film Co., Ltd, now known as Fujifilm. Fujifilm's Fujinon lenses have been used by professional photographers and broadcast stations as well as cinematography. Fujifilm started manufacture of optical glass in its Odawara Factory in Japan in 1940, which was the start of the Fujinon brand. They were proud of their use of expensive Platinum crucibles to get the purest glass achievable at the time. Fujifilm also pioneered Electron Beam Coating (EBC) which according to Fujifilm, represented a new high in lens precision and performance. The EBC process was significantly different from other coating processes by the number of coating, the thinness of the coating, and the materials used for coating. Fujifilm claimed they were able to have as many as 14 layers of coating and used materials such as zirconium oxide, and cerium fluoride, which could not be used for coating in the conventional coating process. The first lens to offer the Electron Beam Coating was the EBC Fujinon 55mm F3.5 Macro in 1972. Light transmission for the coating was said to be 99.8%. EBC later evolved into Super-EBC and HT-EBC.
Jos. Schneider Optische Werke GmbH is a manufacturer of industrial and photographic optics. The company was founded on 18 January 1913 by Joseph Schneider as Optische Anstalt Jos. Schneider & Co. at Bad Kreuznach in Germany. The company changed its name to Jos. Schneider & Co., Optische Werke, Kreuznach in 1922, and to the current Jos. Schneider Optische Werke GmbH in 1998.
The Nikon F3 is Nikon's third professional single-lens reflex camera body, preceded by the F and F2. Introduced in March 1980, it has manual and semi-automatic exposure control whereby the camera would select the correct shutter speed. The Nikon F3 series cameras has the most model variations of any Nikon F camera. It is 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.
A kit lens is a "starter" lens which can be sold with an interchangeable-lens camera such as a mirrorless camera or DSLR. It is generally an inexpensive lens priced at the lowest end of the manufacturer's range so as to not add much to a camera kit's price. The kit consists of the camera body, the lens, and various accessories usually necessary to get started. A kit lens can be sold by itself outside of a kit, particularly the ones that are moderately expensive; for instance a kit lens included in a prosumer camera kit is often marketed as an upgrade lens for a consumer camera. In addition, retailers often have promotions of standalone low-end camera bodies without the lens, or a package that bundles a body with one or two more expensive lenses.
The Nikon F2 is a professional-level, interchangeable lens, 35 mm film, single-lens reflex (SLR) camera. It was manufactured by the Japanese optics company Nippon Kogaku K. K. in Japan from September 1971 to 1980. It used a horizontal-travel focal plane shutter with titanium shutter curtains and a speed range of 1 to 1/2000 second plus Bulb and Time, and flash X-sync of 1/80 second. It had dimensions of 98 mm height, 152.5 mm width, 65 mm depth and 730 g weight. It was available in two colors: black with chrome trim and all black. The F2 was adopted by both casual photographers and professional photographers, the latter of those especially photojournalists covering the later half of the Vietnam War.
The Pentax K-mount, sometimes referred to as the "PK-mount", is a bayonet lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975, and has since been used by all Pentax 35 mm and digital SLRs and also the MILC Pentax K-01. A number of other manufacturers have also produced many K-mount lenses and K-mount cameras.
The double Gauss lens is a compound lens used mostly in camera lenses that reduces optical aberrations over a large focal plane.
The Zeiss Sonnar is a photographic lens originally designed by Dr. Ludwig Bertele in 1929 and patented by Zeiss Ikon. It was notable for its relatively light weight, simple design and fast aperture.
Lens speed is the maximum aperture diameter, or minimum f-number, of a photographic lens. A lens with a larger than average maximum aperture is called a "fast lens" because it can achieve the same exposure as an average lens with a faster shutter speed. Conversely, a smaller maximum aperture is "slow" because it delivers less light intensity and requires a slower (longer) shutter speed.
The Minolta A-mount camera system was a line of photographic equipment from Minolta introduced in 1985 with the world's first integrated autofocus system in the camera body with interchangeable lenses. The system used a lens mount called A-mount, with a flange focal distance 44.50 mm, one millimeter longer, 43.5 mm, than the previous SR mount from 1958. The new mount was wider, 49.7 mm vs. 44.97 mm, than the older SR-mount and due to the longer flange focal distance, old manual lenses were incompatible with the new system. Minolta bought the autofocus technology of Leica Correfot camera which was partly used on the a-mount autofocus technology. The mount is now used by Sony, who bought the SLR camera division from Konica Minolta, Konica and Minolta having merged a few years before.
Cosina Voigtländer refers to photographic products manufactured by Cosina under the Voigtländer name since 1999. Cosina leases rights to the Voigtländer name from RINGFOTO GmbH & Co. ALFO Marketing KG in Germany. Cosina Voigtländer products have included 35mm film SLR and rangefinder camera bodies, and lenses for the M39 lens mount, M42 lens mount, Leica M mount, and other lens mounts.
The Sigma APO 180mm F3.5 EX DG lens was a telephoto/macro lens produced by Sigma Corporation. It contained two SLD glass elements to provide correction for chromatic aberration and was aimed toward advanced consumers.
The Samsung NX-mount is the lens mount used on NX series mirrorless interchangeable lens cameras by Samsung. The mount was first implemented in the Samsung NX10, and Samsung initially referred to the NX line as 'hybrid digital cameras', citing their combination of attributes of both DSLR and compact cameras.
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. In November 2024, Nikon announced the Z50II, the first APS-C camera to use the Expeed 7 processor introduced with the Z9.
The Canon RF lens mount is an interchangeable-lens mount developed by Canon for its full-frame mirrorless interchangeable-lens cameras, and featured first by the EOS R, followed by the EOS RP. The RF mount was announced in September 2018. In May 2022, Canon announced APS-C EOS R cameras and RF-S lenses designed for these cameras.
