ownership:I have experience with this lens
compared to:
price paid:
positive:Very fast focus, very sharp, great colour and little distortion
negative:Stiff zoom control, does not disengage to manual focus using just the AF/MF button on back of 7D
comment:I bought this lens second hand but in top condition, having an F2.8 28-70 on the 7D makes it a very good zoomable standard and portrait lens (42-105 equiv), I would highly recommend this lens even with the stiff zoom control
