Works pretty well with the 24-105mm f4. AF doesn't work, of course, but it's much easier to MF on the 7D than it is with the T1i. I was surprised how much. I had planned on only using my Roki lenses with the T1i, but I may try them out on the 7D after all. This isn't critically sharp because I was shooting at 1/25 instead of the 1/FL of 1/300. The IS is good, but that's stretching it.
