Yes, the standard 35mm Curtagon has a f/2.8 maximum aperture.

That would be fantastic! I just looked it up, it's an M42 lens is that right? How do you focus on the Xpan?
I don't know, sorry. My Curtagon is a 35mm PA-Curtagon f/4 in 35mm ALPA bayonet mount. But, if you can adapt an M42 mount lens to Xpan, a 35mm lens has fairly forgiving depth of field characteristics. So you could likely use the non-shift Curtagon quite effectively as a scale focus lens for general imaging, although obviously, wide open and at close range, much more care would be needed to assure accurate focus.

In really low light, gaining one stop from f/4 to f/2.8 but losing rangefinder coupling seems a bit like taking one step forward, one step back, and then on step to the side. But then again, isn't a lot of photography chasing a series of compromises? 
OP, do you already have a Xpan kit, but just looking for a bit more speed?

The Contarex 35mm Curtagon is an F4 lens and the adapter has no RF coupling. I am used to the Hasselblad SWC so scale focusing isn't a problem for shots from 3 meters. No external finder is necessary. I found if you use the entire built-in viewfinder it is pretty close to what the camera actually sees.

Oh I thought you were saying that it had a max aperture of f/2.8.

Yes I have the first Xpan with the 45mm lens, it's my first film camera. I have a few digital Leica Ms and really fast lenses so it's a huge learning curve for me. I quite often photograph in low light circumstances and have, in the past, photographed theatre, jazz/rock gigs in bars with subdued lighting, or photographed for music festivals in similar circumstances. I've never felt like i needed a wider lens but I have definitely felt the need for a panoramic camera.

Oh man that sounds like several compromises have to be taken. I wonder if Hasselblad (or in reality Fujifilm) would have made faster lenses for the Xpan if digital photography hadn't taken over.
It does.
There is a conventional version of the 35mm Curtagon, the one I believe you have been interested in—and a shift version that permits up to 7 millimetres of rise, fall or cross—the 35mm PA–Curtagon. The former is a f/2.8 maximum aperture. The latter—f/4.
No rise (lens centred):
Maximum rise:
The PA offers the ability to move off axis but comes at the expense of one f stop. Mine seems quite sharp.

Who is delivering these adapters?
Who is delivering these adapters?
with this adapter one can adapt HB-V-lenses easily. HB-C/Y-Xpan two adapters.
measured from 63mm image-circle of the zeiss pc-distagon 35/2.8 i calculated +-5mm shift without vignetting. That lens is very highly appreciated by digital-pros.
I will use it on lookaround rotapancam for 360. NB: there is actually a Roundshot Super 35 on ebay it seems with C/Y-mount-has +-12mm shift. But charger is lacking and cam non-overhauled. too expensive.
Super 220VR with tilthead much better choice.

Who delivers the C/Y-Xpan-adapter? It was shown at photokina and i was so stupid not to buy. reseller is gone.
