Has anybody measured the distance of the focal point for the G1 at
different focal lenghts ?

thank you

I haven't tried it with my G1 yet, but it should be easy enough to do.
Several years ago, I tested my 35mm SLR in the following manner:
(I didn't keep a record, because I felt that it was very easy to do
each time an appropriate focal length was selected for a panorama.)
I have a tripod where the center post which can be turned
horizontally and adjusted back and forth. I used this offset
tripod head to pan my camera with the FRONT of the front of the
lens approximately over the panning axis. With minor
experimentation, I moved the camera backwards and forwards, until
the relative position of near and far objects in the viewfinder
didn't change as I panned the camera. This seemed to work very
well to help make better panoramic composites of film prints.
Would expect that it would work equally well with the G1. Compared
to film, the digital stitching technology makes the panorama
construction a breeze

You are right, the method you used is the good one. But I was wondering if anybody had already measured and tested the G1, just to avoid to do the tests ...since my tripod head don't allow to align properly in two axis and this stupid screw under the G1 is not centered

That's why I need to cut a piece of wood or lastic to act as an interface between the G1 and the tripop ...
