Quote:I do AF reference checks during the MTF analysis.

The results were, as mentioned, fine at f/4 but beyond it was a roller-coaster ride which is typical for not sufficiently corrected RSAs.
 

 

As you2 said, one would have expected a better correction through software, if it's that bad. Seems indeed strange. Firmware update on the horizon?
