Interesting. I thought one of the soon to be released GFX cameras was going to have 100MP. Then again those lenses (while a tiny bit larger than FF) seem to have much better corner sharpness so maybe it will work with that camera ? Then again maybe my memory is faulty ?

People get pretty good results with the 5DS ( R ) too. OL MTF results skew the perception a little (partly due to sharpening). 
Do you have any comparisons between those GFX lenses and lenses on higher res. "FF", which show a much better corner sharpness across the board?
