Thank you Brian. I have currently Don Goldberg finalizing his repair of the Zeiss 35/1.4 and 85/1.4. I will get them back with full aperture control and with perfect focusing. The Zeiss lenses from the 1970's were multi-coated, and they seem to be different from the modern Zeiss lenses that we see being sold in a variety of mounts. I recall that Bob Shell was saying then that whoever did not have the money to buy Zeiss lenses in Contax mount, the Rollei SL system was the way to go to get such lenses for far less money. An ad in Shutterbug had the 35/1.4 and 85/1.4 for sale, and I negotiated the prices down to $400 for both lenses together. I waited for a few years until I sent the lenses back to DAG. He identified internal mechanical problems that were caused by "someone" in the past. He crafted a missing part too. Then he asked me for a Rollei SL35 body so that he could check the infinity focus. He told me that in the 35/1.4 he had to go through multiple focus points because a previous repair job had messed up the lens. I am glad that we still have such gifted repair people.
