Oly 12-40 Pro showing M20 and M60

Nice try Henry, but this is the 12-40 f/2.8 I am using the graph you have posted is for the 12-60 Oly...

Pretty sure it says 12-40 on top line and 12-60 on bottom line in the charts...

yes I also took test shots at 33mm and 32mm on A7r and EM1 respectively, and will post results later...

How do you process? RAW, JPG? Tried both?

Nope, not a focusing problem, corner and side blur due to distortion...hard to correct with a lens so small...

Could be A7r specific - I am actually impressed with how well the A7 holds up with the 28-70 kit lens:
