I bought the Xpan1 w/45mm about a year ago. It is fun. It makes such a big neg on 35mm. I only use the pano mode and not standard unless it's all I have. I don't use it a lot, but I have many cameras and I can't use them all all the time.
If you hold the button on the back down while turning it on, it will show a number that indicates how many exposures have been made. Each unit is ten exposures. Brand new they show 200 exposures.
I've always liked Fuji's idea of advancing the film into the camera and exposing it on the way back into the cassette.
Great optics. I've thought about the 30mm, but it is way expensive and I can't justify.
