35 mm equivalent focal lengths are calculated by multiplying the actual focal length of the lens by the crop factor of the sensor. Typical crop factors are 1.26× – 1.29× for Canon (1.35× for Sigma "H") APS-H format, 1.5× for Nikon APS-C ("DX") format (also used by Sony, Pentax, Fuji, Samsung and others), 1.6× for Canon APS-C format, 2× for Micro Four Thirds format, 2.7× for 1-inch ...
The EF 35mm f / 1.4L II USM is a successor of the EF 35mm f / 1.4L USM. It was announced at the 27th of August 2015 and is available since October same year. [1] The EF 35mm f / 1.4L II USM lens is the first lens in Canon line up to use a Blue Spectrum Refractive Optics element (BR element) to reduce the chromatic aberration at the blue end of the spectrum.

The Canon FD 35mm f/2.0 lens was manufactured by Canon for the FD lens mount. It was sold in several variations after it was introduced in 1971, and was the fastest Canon lens in the 35mm focal length before the debut of the EF 35mm f1.4.
The last version was released in 1992 as a f/4.5 - f/5.6 USM version. [ 3 ] On several recent high-end Canon EOS bodies, including the EOS 7D Mark II , [ 4 ] EOS 5D Mark III and EOS-1D X , the f/4.5–5.6 versions of this lens are treated for the purpose of autofocus as if they were f/8 lenses, limiting AF functionality to the center point (and ...
The same KD series 35mm cannons are used in the Leopard 1 based Gepard and Type 74 tank based Type 87 SPAAG and Marksman self-propelled anti-aircraft guns (SPAAG). The system could be paired with the off-gun (remote) Super Fledermaus fire control radar, which in the late 1970s was upgraded to the Skyguard system.
[4] [5] It is a CIWS variant of KORKUT Self-propelled anti-aircraft gun. [6] [7] Each GOKDENIZ platform carries a variant of Oerlikon 35 mm twin cannon, manufactured under licence by MKEK. [7] The CIWS system, sensors and electronics manufactured by Aselsan. The CIWS can fire up to 1100 rounds a minute up to an effective range of 4 km. [4] [7]
So a standard 50 mm lens for 35 mm photography acts like a 50 mm standard "film" lens even on a professional digital SLR, but would act closer to a 75 mm (1.5×50 mm Nikon) or 80 mm lens (1.6×50mm Canon) on many mid-market DSLRs, and the 40-degree angle of view of a standard 50 mm lens on a film camera is equivalent to a 28–35 mm lens on ...
Comparing the film area of Super 35 (framed for 2.39) to CinemaScope, standard widescreen and Techniscope. Super 35 (originally known as Superscope 235) is a motion picture film format that uses exactly the same film stock as standard 35 mm film, but puts a larger image frame on that stock by using the space normally reserved for the optical analog sound track.
