You joke. I know you know the Rolleiflex is 120/ 6x6. Barnack was one of the first 35mm designers. The designer of the Ihagee Kine Prakitca is in the running too. Modern cameras are still based on his design.
I have a Leica IIIc (1942) and have been using it as my primary camera.

Seem to be forgetting that Rollei also sold the SL35 cameras and had the SL2000 and 3003 cameras which looked like miniature medium format SLR's... :-P
