I've always been intested in pano cams but their price for even the FSU examples (Horizont) have somehow kept me away from them. I know the Horizont / Noblex philosophy is different from the X-Pan but the Horizon is probably the most affordable panoramic camera apart from the APS format, of course.
I've seen some people using the X-Pan for street shooting, not to mention it gives a completely new perspective for that kind of shots so it may be a field worth to explore.
No ?
