I'm getting a huge number of very soft images from my 24-105L using a 40D and I'm wondering if calibration would help. I can't micro adjust on the 40D itself.
I have also yet to get around to setting it up on my tripod and doing a set of proper focus tests but in comparison to my 50mm and 10-20mm lenses, the 24-105L appears to be focusing quite badly.
I have tried combinations of focus points, focus modes, everything I can think of, yet I'm getting soft images (not all the time but a high percentage). This is with AF On of course.
Has anyone seen any improvements in sending their lens off to Canon for calibration.
