Yes, this could be calibrated out, with a more complex RF cam or a non linear focus tube.. but in 1969 (?) when the Nocti was designed, it did not make any difference......and that legacy is what you are dealing with. Maybe Dr. Yao's suggestion of a 50 F0.9 might have this built in..... it would be pretty easy at this stage of technology. Frank Filippone red735i@earthlink.net if you got the most critical of your lenses right with the RF cam adjustment, the rest of your lenses should fall into place.
