Not true... the issue is focus plane changing with different subject to
camera distances....... on only 1 lens ( or maybe a couple, but particularly
bad with the Nocti).....the others are just fine.

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.

if you got the 
most critical of your lenses right with the RF cam adjustment, the rest of 
your lenses should fall into place.
