Has anyone used this combo?
If so, how does the lens perform on the Mark III?
I've read a review or two saying that the MKIII will show the "shorcomings" of "Non - L" lenses. I'm wondering if I should take this with a grain of salt, or will the new body
accentuate problems that may not be apparent with say a 7D or a 60D?
I'll probably get the 24-105 along with the 5DM3, but my zoom is going to be
(at least for a while) the Sigma 70-200 2.8 OS.
