"...the A20/2.8 goes pretty mushy in the corners...."
Hmmm. This is the first negative comment I have seen on this lens. I have ordered the FA 20 f2.8, which has the same optical formula, based on rave comments and an online photo showing good sharpness at f2.8. Well, come to think of it, that image had good center sharpness. The edges were out of focus. I do hope I haven't made a $500 mistake.
Rob, can you clarify at which f-stops you've noticed corner mushiness? I will be using this lens indoors, mostly at f2.8, on the D.
