Dreaded question: is my 24-105L soft?
Oct 2, 2006

I have always felt my 24-105 is not as sharp as my other lenses. The following are 100% crops from a picture I took today, no processing.

Camera setting: ISO 100, f/13, 1/100s, IS on, focal length: 105mm (but the softness seems to be uniform across the focal length range).

1/100s should be plenty for this focal length, plus the IS was on. Other pictures I took on a tripod, with IS off show the same softness.

What do you think?
