While the 55mm FE lens is the best autofocus lens ever tested I noticed on the DxO interactive graph that the new 90mm FE G lens is actually the sharpest lens in their database. Even sharper than the $4,000 Zeiss Otus lens line!
This also means I changed my mind and I will go for the FE 90mm macro and not for the Batis :)
