Not as guro as I had thought by Klaus's earlier comments - in fact smth like the EF 24-105/4 L II seemed to have fared even worse on the 5DSR IIRC - but still not something I would consciously get for my own $/€/₽. The 24-85 cost me $90 - though it came without so much as a front cap - so I'm willing to look past its shortcomings, but $400 for this one looks a bit steep. As Klaus has rightfully pointed out, one doesn't usually buy expensive FF bodies and put any junk on them (not even "the cheapest" in this case) hoping that "FF magic" alone will help.
Let the "coke bottle" designation stick. You certainly get a lot of distortion and vignetting looking through an actual coke bottle LOL.
