Equipment Model: Helios-44M 58mm 50mm f/2 Russian lens fits M42
Price (S$): 95
Description:
The Helios-44M 58 mm f/ 2 (Russian: "Гелиос") is a fast standard lens for a M42 screw mount. Focal length: 58,6 mm Angle of view: 40° 28' Light diameter of first surface: 29,5 mm Light diameter of last surface: 24,7 mm Geometrical vignetting: 58% Mimimal aperture: 1:16-1:22 Maximum diameter of a barrel: 60-64 mm Weight: 230/270/300/350 gr The Helios 44M is six lens anastigmat with a single coating or multicoating (MC). It's prototype was Biotar 2/58 (Carl Zeiss Jena). By optical design it is Planar. It was one of the most spreaded lens in USSR and it was a kit lens for Zenit cameras. There were several modifications of Helios-44. Different mounts: Start-bayonet, M39, М42 and К-bayonet (Pentax). In 70s manual diaphragm operation changed to the instant-return diaphragm thus added letter "M" to lens name. Letter "K" instead of "M" means K-mount (Pentax). In earlier versions there were 13 or 8 diaphragm blades but in latest versions only 6 blades were placed. Helios-44M is sufficiently sharp. Maximum of sharpness can be achieved at aperture F5.6-8. Lens has a nice bokeh but sometimes it turns "swirly bokeh". I haven't seen CA while using this lens. Helios-44M 58 mm f/2 is a multi-purpose lens. You can do all range of work: from portrait work to close-ups with using of extending rings. All versions of this lens are very similar but they differs in resolution. Important role is played by quality of assembling of a specific copy. Helios-44M is not flare-resistant thus a hood is recommended. Sometimes is hard to focus cause of a long run of a focusing ring (270 degrees) - you have to find a middle of an in-focus-zone. It can be achieved easier using LiveView 10x. Resolution (center/edge): 38/19 lp/mm
The lens is in EXCELLENT condition (see actual pictures). All are in working condition. The focus and aperture change smoothly. The lens is free of scratches, cleaning marks, fungus inside.
