I'd curious to hear if Mark(Chap) has any Live View focusing issues(on his Canon)

generally(that means approx 99.9% ) this lens is still surprising me with it's all round quality
Now that you mention filling the AF sensor with the subject, the shots that I missed would have been the ones where the canoes were a long way off and they only sit inches high in the water any way so the subject would not have been filling the AF sensor

Arthur, I very rarely use live view for anything, maybe some macro stuff, to confirm framing etc, the screen on the 40D isn't exactly the best. Don't even know how to get AF to work with live view
