As an aside, despite having access to whatever cameras and lenses he wanted, my father bought a Zeiss Contaflex III in 1957 and has used it ever since. Günther Leitz, with whom dad was a friend, gave him a beautiful Leica IIIg and collapsible Summicron when my parents got married in 1959, but it’s still in the box at their house. My father’s view is that the Tessar in the Contaflex is soft-sharp, with good resolution but moderate contrast. It also had enough edge falloff and change in performance between wide open and stopped down, that he could use it how he liked. A lot of his people pictures were shot wide open, but scenes were usually shot at f5.6-8. He was an engineer who understood what the things he worked with were for, and how to get what he wanted out of them. He has a modest but good record of our family life, but if I learned anything from looking at his photos it was to shoot more Irrespective of what camera I had.
