Oh, I didn't recall your having done that. Now I feel better about taking
mine in. It's either the lens, the camera, or me. Hopefully it's not the

Did you happen to check the diopter setting on the camera?

Your lens may be focusing properly, but you're not seeing it because
the diopter may be off.

Ask me how I know that. :)
