I, too, am a recent convert from a 40D to a 7D. Actually, I trust the 40D so much I'm keeping it, maybe for the macro lens when I can get close enough. I figure the additional pixel count on the 7D will enable more cropping flexibility when I can't get close enough at all.The 40D seemed to have trouble "seeing" very narrow damselflies and had trouble focussing. With a dedicated focussing processor, the 7D should respond better than my old faithful at which I'm frequently heard to scream, "just focus damn you".
Thanks John and Stephen will try out AI-Servo, at the moment I use one shot can see that AI-Servo would be helpful in breezy conditionsAm looking forwards to getting started Just need the weather to improve and warm up there's no sign of anything yet
Probably a daft question but will it make any difference to the is on the 100l macro using is servo rather than single shot ?With single shot when I press the shutter the is settles and the lens focuses and get a beep and take a shot but is the lens is focusing continuosly does that mean that the is won't be as stableWhat I mean is that on single shot can get down to quite a low shutter speed and get Sharp shots if the lens is focusing continueosly in AIservo does it mean that the is won't be as effective ?
I am also going to try using M-Raw (approx 10Mp) and see how it compares to L-Raw (approx 17Mp) - mainly based on this article http://www.kenrockwell.com/canon/7d/users-guide/. Stephen
