While I dream of the xpan :-) I've been playing with an adapter to use 135mm in medium format cameras: FAK 135, by camerhack.it -
It's really funny!! I used the Pentax 6x7 with the waist level finder. I love it!
Puerta del Sol is the heart of Madrid!

That's kinda cool - grat result !
I tried shooting 135mm with the Broni ETRSI 135W back for 24 x 54mm - I remember loading was way too fiddly and complicated for my paws ...
I gave it away for a reasonable price and crop my 120 to the same size (I still have the panoramic focussing screen installed).
