Re: G1 nodal point

Forgot one important question (told you I'm not the brightest) is it the focal length that matter or is it the accurate position of the camera on the tripod that matters? After all we set it usually to widest angle... or am I missing something?

Hi Alain

Thanks for this post. I have been doing panoramas at work for
nearly 30 years none on a tripod and never too concerned with
accuracy of nodal point. That could mean two thing 1-I am not the
brightest... 2-It is not that critical - at least not for my use.

With digital I either use the viewfinder but than can't use the
pano stich or use the pano stich but than need to get the camera
even further than the axis of my body/head and errors mounting.

Thanks for bringing it up and many thaks the guys who responded -
great information

Thanks for the links, I'll visit those sites.
You are right 2 measurements full tele and full wide would be a
good startpoint !

digitalkamera.de has a chart of nodal points; however, the G1 is
not listed. Once one of us determines the G1 nodal points, they can
be submited.

digitalkamera.de's guide to finding your digicam's nodal point(s)
is here:

panoguide.com's guides to finding and testing found nodal points:

What bugs me about finding nodal points for the G1's zoom lens is
that there's no numerical indicator of zoom length while shooting,
so we have to nodal for either of the 2 known zoom values of
extreme wide or extreme tele.

To generate proper panorama, it's best to rotate around the nodal
point so that to points at different depths keep aligned during

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

thank you
