When manually focussing the G1 this is what I do: I roughly focus and when it looks near enough on the screen I hit the 'left button' (left of the menu/set button) and then hit the menu/set button to enlarge the screen so I can fine focus. So that's two buttons to push to get to fine focus. Is there a way to program the camera so I can hit just the one button (like a way to program the Fn button) so I just push the one button and the enlarged screen is displayed, rather than pressing two buttons to do it? I'm very lazy. Any other tips on manually focussing would be welcomed too.
