I should have been clear that I'm posting 100% crops. These aren't really extreme close-ups.
A shutter speed of 1/160 at 70mm should be enough to stop motion blur, should it not? I was under the impression that 1 / 2x focal length with a FF camera would be sufficient. And the first picture at 50mm is 1/640.
I have calibrated the 24-70 with FoCal, and it returned a zero adjustment at 24mm and a -1 at 70mm.
I agree that a tripod and static subject would be a more controlled test. But I'm also interested in seeing how a lens performs in my normal shooting conditions. My 50/1.4 is very sharp above f/1.8 in normal shooting using the same technique and settings I used for these pictures. The same is true for my 40/2.8. The lenses I've had issues with are the Sigma 35/1.4 (obviously front-focusing by a significant amount), Sigma 85/1.4 (erratic focus) and possibly the 24-70 II (*maybe* slightly soft wide open, especially at 70mm).
Today I will try a more controlled test and see what I can learn.
And yes, perhaps I should send the 5D3 into Canon — with the 24-70.
