Me also. I like the mark III and 100-400 more. I find the 7D and the Sigma at 500mm really needs a tripod to get sharp. I do waffle back and forth between the two. It has gotten to where when I go birding I take them both just in case.
What has your experience been with the 5DIII and the Sigma lens? I believe I have a sharp copy of this lens and have been very happy with this pairing. I think the color/saturation is slightly better with the 100-400L but the Sigma on the 5dIII had been impressive.
I also bring both with me. Typically its the 5dIII/100-400L and the 7D/Sigma. That said, I intend to spend a little more time with the Sigma on the 5DIII.
