Extremely interesting post here:
LensRentals.com - Sony E Mount Lens Optical Bench Tests
What stunned me was the copy variation.......of the Otus!! And other lenses also. FE 90/2.8 is not quite the dragonslayer I thought, and has huge copy variation.
Also of note is the Sony lenses need optical glass in the path to work right......
I hope to see something besides WO, or am I missing a link?
