Helios 44
Helios-44 is a series of standard lenses for SLR cameras, produced in Soviet Union by KMZ, MMZ, and Valdai from 1949? until 1992 (2001?). It is it is considered to be one of most mass-produced lenses in the world. The lens is based on the Carl Zeiss Biotar f/2 58mm design.[1] The Helios-44 f/2 58mm is a 6-element anastigmat, which over the duration of its production was available in both single-coated and multi-coated versions. Helios-44 is has a strong aberration at the margins, resulting in a characteristic 'swirl' which is reminiscent of Petzval lenses.
The nomenclature Helios lenses follows the formula '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).
Typology of the silver-barrelled Helios-44 lenses
Helios 44 (Start)
- 'Type 1'— f-stops to f/22; bezel text that spells out '1:2 F=5,8cm' with a cyrillic P in red, silver front bezel ring[2]
Helios-44 (LTM)
- 'Type 1'— f-stops to f/22; bezel text that spells out '1:2 F=5,8cm' with a cyrillic P in red, silver front bezel ring
- 'Type 2'—f-stops to f/16
- Type 2a—bezel text that spells out '1:2 F=5,8cm' with a cyrillic P in red (e.g. sn 0018687) and a silver front bezel ring. [3]
- Type 2b—bezel text "2/58" and the 'silver' front bezel ring produced by KMZ
- Type 2c—bezel text "2/58" and 'black' front bezel ring, 13-blade diaphragm produced by KMZ until the late 1950s
- Type 2d—bezel text "2/58" and 'black' front bezel ring, 8-blade diaphragm, produced by KMZ until the late 1950s

'Helios-44-2 (M42)
- Type 1—bezel text "2/58" and the 'silver' front bezel ring produced by Valdai
