First of all, something is wrong. This is *not* the way a perfectly executed picture from the 5DII should look.


By 100%, do you mean this is the whole picture, or cropped so the pixels are seen 100% size? In either case, the 5DII can make pictures that are far sharper than what you have here. Note, though, that the 5DII and rebel XT have the same size pixels, so if you crop them to 1-1, I expect the pics to look similar at very low iso (which means the 5DII should look much sharper when you look at the whole picture).


As others have said, either you messed up somehow (missed focus or, less likely given the high shutter speed, camera shake), there is something wrong with the lens, or there is something wrong with the camera. It is tempting to rule out a problem with the lens since it got good pics on the rebel.


Are you unable to get any picture sharper than the one you've shown? How about the pictures you took to do the calibration... are any of them sharp? Use a tripod and manual focus at 10x with live view and use a very high shutter speed. Stop down. Can you get a sharp picture then?





There seems to be a lot of texture in the out of focus portion of the image and in the model's neck. When I saw that I thought the picture was taken at high iso, and I'm surprised to see it at iso 100. Did you apply heavy sharpening to the image?

You should adjust focus with the widest aperture possible, not the narrowest.
