Your subject(s) wasn't in motion (in three dimensions, I might add!)! :-) But I do agree that focus is the real challenge. Manually focusing on a moving subject with the fov of a 900mm lens is very difficult. Especially since the focus ring of the Sigma only moves about 1/4 turn when manually focusing. I use just the thumb of my left hand to turn it since it is so sensitive. PS: I was wondering what the 100% crop would be. you disappoint me, Mr. Studdert..... -- Christian [EMAIL PROTECTED]
