Helios-44 is a series of standard lenses for SLR cameras, produced in Soviet Union by [[KMZ]], [[MMZ]], Jupiter from 1958 until 1992 (2001?). It is it is considered to be one of most mass produced lenses in the world. It is based on the [[Carl Zeiss]]  Biotar 2 / 58. At the beginning was to be called "БТК" - "БиоТар Красногорский" (BioTar Krasnogorski). A fast 6-element anastigmat, it was available in both single-coated and multi-coated versions.

The name of Helios lenses are usually writen as Helios-44X-N, where X -is the index of lens mount (M for m42 thread, K for Pentax K bayonet, Д for Zenit-D bayonet) and N is a optical resolution index 2, 3, 4, 5, 6, 7 (the higher number the higher is an optical resolution of lens).

While technically a high speed cine camera, shooting at 100 frames/second, the  resulting negatives were not projected as a film but examined individually in order to assess the miss distance of the missile in relation to its target.

Helios 44. Optical Scheme
−
The film magazine took a standard 50ft roll of 35mm cine film, which gave the camera a run time of 12 seconds.
+
Focal Distance: 58mm (may vary in real)

Optical Formula: 6 elements in 4 groups.

Aperture Range: f/2 - f/16. (f/22 later)

There is no readily visible difference between the Mk1C and Mk1D models, either in overall appearance, lenses or mechanics.

Helios

Helios was a type of camera lenses, made in the USSR. They were usually supplied with Zenit SLR cameras and thus usable with other M42 lens mount cameras. Some later Helios models were built also for the Pentax K mount.

The Helios-40 and Helios-44 and are derivatives of the Carl Zeiss Biotar optical formula.

Helios 44

Helios-44 is a series of standard lenses for SLR cameras, produced in Soviet Union by KMZ, MMZ, Jupiter from 1958 until 1992 (2001?). It is it is considered to be one of most mass produced lenses in the world. It is based on the Carl Zeiss Biotar 2 / 58. At the beginning was to be called "БТК" - "БиоТар Красногорский" (BioTar Krasnogorski). A fast 6-element anastigmat, it was available in both single-coated and multi-coated versions.


The name of Helios lenses are usually writen as Helios-44X-N, where X -is the index of lens mount (M for m42 thread, K for Pentax K bayonet, Д for Zenit-D bayonet) and N is a optical resolution index 2, 3, 4, 5, 6, 7 (the higher number the higher is an optical resolution of lens).
