I've had my 50mm 1.4 for nearly a year now and I've always been disappointed at it's lack of sharpness. Well, I take that back. After getting a 7D last week and adjusting for the lens, I'm getting pretty damned near tack-sharp at 1.4!


Currently, my only other lens is the 28-135 IS (I know, I need a wide-angle). I've read a few sites that suggest adjusting the lens in the widest setting, others say use your most common focal lengh (it's a zoom, I use the whole range). I was wondering what you guys would recommend, or have done with your zoom lenses.


Thanks.
