To complete the discussion, the only real differences between Fuji Tx-1 and Hassy's X-pan 1, is cosmetic. Fuji uses the gun metal surface like their GA645zi, while Hassy uses a painted black finish. Unfortunately, the painted black has a tendency to scratch and brass, and so the Hassy version usually looks worse for wear quicker than the Fuji. Both companies version 2, however, are black, and appear to have a better, thicker, baked surface enamel. As for differences between the old versions (the "1" of both companies) and the new (the "2"), there are several, but the most important, I think, are the following three features: (1) the new versions allow a longer "B" time frame (for long night exposures), of 9 minutes (over just 30 seconds on the "1" versions); (2) the new versions allow multiple exposures where the old ones don't, and (3), shutter speed information can be read through the viewfinder during composition, while the originals don't allow it. Other improvements involve better sealing for infrared film, a film rewind that leaves the tongue outside the cartridge, and so forth. Which do you need, the original version, or the new version? By answering the following questions, you can probably decide. Most folks don't take multiple exposures, so don't need that capability (favoring the "1"). Most folks don't take ultra long night shots (favoring the "1"). However, many folks like to see shutter speed info while composing their pictures (favoring the "2"). With that said, I virtually always use my X-pans for panoramas, and virtually always use a tripod. So, I can easily access composure information reading the back LED panel. (back to favoring the "1"). That, and the fact that a "1" can be purchased for less than half the price of a "2", should at least keep some of those "1"s in circulation. As I mentioned, though in my first discussion, I have two of the original, and one "2", since in fact I do make both multiple exposures, and once in a while, take real long shots. Hope this helps.
