| hehe... would you describe the MF feel as "sandy" or difficult to move?
As for the corner sharpness lost, I think this may be exhibited on my Sigma 24 F2.8, which (even when stopped down to F4) is very soft on one area. It could be a lens element out of alignment also. hmm...
By poor edge quality... does this mean that if my subject is in the corner, he/she/it will be strangely soft? |
