All my lenses work great on my R (and 5D series bodies too), except I finally took out the 300/4L, the old non-IS version, and it won't give me good focus on the R.
I did some testing, and here's what I found:
Autofocus - no matter the spot, one shot of course, and its pretty much off. I think I said backfocus issue on another web forum, but its actually front focus.
Manual focus with peaking - off like AF
Manual focus with triangles - off like AF
Manual focus with 10x - spot on, as good as with my 5d series cameras. The 300/4L doesn't need "correction" with any of those bodies, btw.
Should also add that its the same with the old "regular" 1.4x as well, except more pronounced.
So... I contacted CUSA, and we'll wait and see what they say.
