The one alternative for 135 pano that completely went over my head was the Holga 135 pan. It's incredibly cheap and can be a good way to experiment with pano.
>>2940906There's pano backs for the Bronica S system, I believe one for the E series too. Hassy had a 56x24 back. The Mamiya /7 had a 135 adapter too which is again 56x24. I believe the rest were generally hack jobs or mounting the spools. The Mamiya 645 135 back isn't true pano so avoid that.
They work well, extremely well and you have a large lineup of lenses you can use with them. What you do have is generally a lot of weight on anything but the Mamiya 6/7 as you are shooting MF SLR's. A complete kit with lens/prism/back will usually weigh about 2-3 KG while the Xpan is around 1.1 KG iirc.
>>2940897Yeah, that's the big concern of owning one, one day it could fail. Until then enjoy it.
As for pano being a gimmick, it really can be. A lot of people feel that just because their images are now shot on a pano camera or an anamorphic lens that this makes them great when in reality you still need a clear vision. My buddy put a roll through the Xpan and he was super excited to get to shoot one, but he was disappointed with the results because he just couldn't make it work.
That's why I would recommend shooting digital at a 24mm eqv and cropping that ratio strictly until you know you can make it work. If you give it up after a few weeks or months, you've saved yourself the hassle of buying/reselling an xpan.
