The reason why I asked was to find out if the varying Shift values would cause
problems/errors in PTgui, and if you would have to use individual Shift parameters for
each image. It appears to be less of a problem than I thought it was?
My only IS camera at the moment is a Panasonic P&S, which I will not use for spherical
panos (35mm lens), but I was considering one of the new Olympus SLRs, with IS in the
body.
I have actually had some problems, even with the camera on a tripod, in windy/gusty
weather and long exposure times (30s).--
