I thought this an odd question- but then from 1979-81 I used a Bronica ETR on the job as a high school yearbook photographer. I made who knows, thousands of group portraits and "candids" for many, many yearbooks. I had one lens, a 75mm, and everything was lit by two big Metz 45 'hammerhead' strobes. So most exposures were around f/8 (?) and the 8x10 prints looked fine. A very good camera (supplied by the studio I worked for) and no one ever saw, or said, anything bad about the lenses.
However, at this late date I have no idea which iteration of the lens was the one I used, so this comment is likely to be useless.
