Cat. No. Zenit-Helios-85mm-f1.5-M42
Zenit MC-Helios #40-2 85mm f/1.5 lens in M42 Mount
The fast Helios 85mm renders very differently than the Zenit 85mm f/1.4 even though their max apertures are close. The Helios 40 series lenses historically have been derivates of the Zeiss Biotar optical formula and the new 40-2 Helios follows in that tradition. They produce an unusual "swirly" effect to the background bokeh. Lights or specular light (such as light coming through foliage) will be rendered as large circles. Quoting the Wikipedia page for Helios - "The bokeh "circles" become more elliptical in shape as you move away from the center of the photo. This optical phenomenon gives images rendered by these vintage lenses a distinct character, which has created a cult following among fine art photographers."
The new Helios lenses have a special aperture adjustment ring set up - you set the smallest aperture you wish to use with a click stop ring, then another freely turning aperture ring allows you to quickly open up the lens for easier focusing wide open.
The M42 mount can be adapted easily to other cameras such as Canon or Sony with adapters. When buying adapter rings, you need only the V1 style since there is no pin on the rear of this lens.
