| p.2 #1 · Is your 24-70 II a little soft at 70mm? |
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.
first, just try some fast shutter high-contrast, low to moderate ISO, 10x zoom liveview manually focused shots and look at the best ones, if those look bad then you know the optics are bad
if those are good, then you may be getting shake (even on a tripod, if you don't use liveview mode you can get mirror slap shake which can make a mess, or if you don't let it settle down since many tripod, even sturdy still have a bit of bounce after you touch the camera) or poor AF (either due to the body or lens or simply poor MFA)
