Zeiss Ikon Contaflex Super B with 3 lenses and interchangeable film back with cassette. Nice set.

The Contaflex Super (new) and Contaflex Super B are very similar cameras. Both have a new body design, both longer and more bulky. The information about which came first is a bit contradictory in some reference books, but it seems the Super (new) was launched in 1962, introducing the new body design and a new selenium exposure meter in a prominent rectangle marked Zeiss Ikon in front of the prism. The aperture wheel was replaced by a more traditional aperture command, and the meter read-out was visible both on the exterior and in the finder.

The Super B was launched in 1963, and added a shutter-priority automatic aperture, and maybe some other small changes.

The new body of the Super (new) and Super B allowed them to take magazine backs, interchangeable with a partly exposed film inside. (Magazine backs, rare among 35mm cameras, were also supplied for the Contarex of Zeiss Ikon.)

From the Super (new) and Super B, the Zeiss Tessar 50mm f:2.8 lens was recomputed and supposedly performed better.
