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).
