Peter, That is a quite unfair comparison. The Contaflex was squarely aimed at the consumer market. It had interchangeable front sections much like the Retina IIIc rangefinder camera. The rear group of the Tessar stayed in place behind the shutter and the front sections were replaced with either the 35 or 85 Pro-Tessars. Not pro grade at all, although very nicely finished cameras. The Contarex was the be all and end all of the Z-I camera line. It had a focal plane shutter, instant-return mirror (interestingly though, not fully automatic diaphram). The lens line was complete (with many quite fast lenses), to say the least. The 85/1.4 Planar was originally produced for the Contarex. The Contarex lens line are the exact designs produced for the Rollei SL35 cameras. The third generation Contarex design was sold to Rollei at the end and became the SL2000. It wasn't any attachment to leaf shutters that kept Z-I from competing with Canon and Nikon, it was price and ergonomics. For a full description I recommend Marc's book on the post war Zeiss-Ikon cameras. David Peter K. wrote: >ContaFLEX.
