I've noticed a few threads giving the 24-70 a bad review, and people have even suggested they should take the lens in for repairs.
I've just bought the 24-70 L and 7D, and I'm still on the learning curve. Results so far have been 50/50. The keepers are good....very good. The other 50% are so-so, but I've put them down to user error.
In light of people giving this lens a bad wrap, is there any cause for concern?
