A TRUE GEM IN ANY COLLECTION!
This is the early post-war chrome m42 version with preset aperture and 17 aperture blades – one of the early post-war variants, before the later 12- and 10-blade versions. The 17-blade diaphragm keeps out-of-focus highlights round even when stopped down. The focal length is still engraved in centimetres (“f=5,8cm”), and the red “T” marks the Zeiss anti-reflection coating.
The lens s/n 3349234 was made in the early 1950s.
It is a very heavy, solidly built all-metal lens.
Lens barrel has light signs of age and use.
Glass: micro scratches on the front element; blemishes on the coating of the rear element are present but seem to not affect image quality.
Mechanics are excellent.
Small amount of clear oil on the aperture blades – does not affect functionality or image quality.
See photos for cosmetics.
Creates beautiful Biotar style bokeh – out of focus highlights are rendered as beautiful discs, making the background swirly.
Comes with original Carl Zeiss Jena front cap and rear cap.

Why Collectors Want This Lens Today
The Biotar 58mm f/2 is the lens the Soviet Helios-44 was copied from. Zeiss introduced it in 1936 for the Kine Exakta, to a design by Willy Merté, and after the war Carl Zeiss Jena kept making it until about 1960, with 17-, 12- and 10-blade diaphragms and with manual, preset and semi-automatic aperture control. The Helios-44 became one of the most mass-produced lenses in the world; the Biotar is the German original behind it.
This example is one of the early post-war versions with a 17-blade diaphragm, still engraved in centimetres (“5,8cm”) and marked with the red “T” of the Zeiss anti-reflection coating. So many thin blades keep the opening close to round when stopped down, so out-of-focus highlights stay round too. It is the same quality collectors look for in the early 13-blade Helios-44.
