I used to owned a EX DG APO version for A mount before I jumped to Canon;
all I must say- its' image output is as sharp as a Canon 70- 200mm f/2.8 L which I'm owning 1 piece now.
Focusing speed is slower than Canon version as Canon version have the USM.
I sold it to my fren and he is very happy with the lens's performance.:thumbsup: :thumbsup:
ps:- My migration to white side was completed.
