Caveats of the analysis:
Speedbooster ultra used--probably the .71 not the 0.64 version. Both INCREASE
MTF and eliminate the effect of sensor stack. Stack issue minimal at these
FL's though but MTF improvement
could be interesting and is Speedbooster use still results in a crop also
affecting the results vs FF. I still suspect the PL will be much better but
explains how useful the lens can still be on MFT.
The 0.64X version is apparently risky to use on E-M1 mkx cams--drat. It has
been done however.
Don't forget the Speedbooster, Mike
