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 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
  • '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.
Type 2b—bezel text "2/58" and the 'silver' front bezel ring produced by KMZ
Type 2bi— Cyrillic labelling [1]
Type 2bii—Latin labelling, engraved "Made in USSR'. [2]
Type 2c—bezel text "2/58" and 'black' front bezel ring, 13-blade diaphragm produced by KMZ until the late 1950s
Type 2bi— Cyrillic labelling
Type 2cii—Latin labelling [3]
Type 2d—bezel text "2/58" and 'black' front bezel ring, 8-blade diaphragm, produced by KMZ until the late 1950s
Type 2di—Cyrillc labelling, engraved "Made in USSR'. [4]
Type 2dii—Latin labelling, engraved "Made in USSR'. [5]
Type 2e—bezel text "2/58" and black front bezel ring, 8-blade diaphragm, produced by MMZ until the 1960s
Type 2ei— Cyrillic labelling [6]
Type 2eii— Latin labelling [7]
