180mm f/2.8 Carl Zeiss Jena Sonnar

A sharp, high contrast lens from the Deutsche Demokratische Republik

The 180mm f/2.8 “Olympia” Sonnar was originally designed for the Contax rangefinder camera in 1936. The Sonnar used for this video was probably manufactured after 1975 because of the multi-coating (MC) designation and serial number above 10,000,000.

Due to its size, the lens appears heavier than what it is, 1.51 kg with a Pentacon Six/ EF lens adapter and lens hood.

This Sonnar, in P6 mount, was made for the medium format Pentacon Six camera. With an EF lens adapter, the 5D Mark II sensor uses the 36 x 24 mm area in the center of the image circle, the sharpest portion of the 60mm by 60mm film plane.

The 180mm f/2.8 Carl Zeiss Jena Sonnar needs an image circle large enough and sharp enough to cover the 60mm by 60mm film plane.
