Aperture selection with f-stops increasing in clockwise motion. Moreover, the lens for the Start lacks the preset function of the other early models. Mechanically, the Helios lens for the Start SLR differs from all other Helios-44 lenses inasmuch as the focussing ring is up front and the aperture selector at the rear. Observed have been N and Nº, whereby the 'N" appears on some of the earlier models.

The early Helios lenses are housed in aluminium barrels. Typology of the silver-barrelled Helios-44 lenses (early versions) In the table below, the arrow ← indicates the direction the aperture control ring needs to be turned to increase the ƒ-stops. The arrangement of the focussing helicoid as well as the aperture selector ring differs between models. The nomenclature of all bar the first (silver-cased) 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).įocal Distance: 58mm (may vary in reality). Helios-44 is has a strong aberration at the margins, resulting in a characteristic 'swirl' which is reminiscent of Petzval lenses. 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. The lens is based on the Carl Zeiss Biotar f/2 58mm design. The Helios-44 is it is considered to be one of most mass-produced lenses in the world. Helios-44 (Гелиос-44) is a series of standard lenses for SLR cameras, produced from 1949? until 1992 (2001?) in the Soviet Union by KMZ, MMZ, and by Valdai.
