Jono, in my brief time w/the G1 so far, *in which I've come to the camera on it's own terms* (not expecting to use it in exactly the same way as my other cameras -film...), I've not noticed an obstacle to capturing the moment I see for the shot --assuming that moment is viewed on one of the G1's screens. Now if you wanted to shoot w/out looking through/at the camera, then you're SOL. You have to accept the screen time as where the action takes place, and I think you can stop that w/fair accuracy.
(disregard all of the above if you're moving the camera fast in lower light, though, when the randomness principle will just about Completely take over.):clap:
