We had a chance to load up an XPan with Kodak Gold 100 film and use for a half-hour with the 45mm lens. It feels very solid, and has a quiet, positive action reminiscent of the Contax G2. The extra body length provides plenty of space. Focusing is light but stays put, and the extra long base of the rangefinder provides clear settings even at around 20-30ft. The results were perfectly exposed by average metering standards, and very sharp indeed.
Camera shake is negligible as the body is fairly heavy and hand-holds steadily.
A 35mm ultrawide and 135mm tele are likely additional lenses. No duplication without express permission.
