Um actually, both are sharp. AF speed does not help in sharpness, AF accuracy does. :bsmilie:
As you have use this lens before, do you feel the AF accuracy difference for SWD and non-SWD version?
While I have the 12-60 SWD i feel it stick to focus much better than kit lens. However it should compare to similar older brother 14-54 I or II, which I don't own any to try. :bigeyes:
