It's an obvious thing, but I'll point it out anyway. The Fotoman and the Xpan are completely different kinds of cameras. The Fotman relative to the Xpan is big, and heavy, and wears a large format lens in a shutter on a helical, and makes 7 inch wide negatives. The Xpan compares as small and light, and behaves in a much more conventional fashion, and makes much smaller negatives. Their respective strengths and weaknesses are practically opposites. A careful consideration of what and how you are shooting, and what your final intention is, will reveal the proper system for your work.
