I shoot with a 7D and I would love to know peoples thoughts on this lens, preferably people who own the lens - I'm not after uninformed forum-based opinion from specifications or speculation but real, honest advice about results and reliability
how good is this lens? what's the build quality like? is it sharp throughout the zoom range at f/2.8? (even though I'll mainly use it with off-camera flash at around f/4- f/11) is it worth the money or should I buy L series (16-35 / 17-40 ) and adjust where I shoot from?
many thanks
