Helios-44 is a series of standard lenses for SLR cameras, produced in Soviet Union by KMZ, MMZ, Jupiter from 1958 till 1992 (2001?) and it is considered to be one of most mass produced lenses in the world. Based on the lens Biotar 2 / 58 , at the beginning was called "ะ‘ะขะš" - "ะ‘ะธะพะขะฐั€ ะšั€ะฐัะฝะพะณะพั€ัะบะธะน" (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, ะ” 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).
