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!
This is San Ginés Street, where the most famous churrería of Madrid is located

@David Lyga Thank you, David!! As I've said in the comments of the bridge photo, I think is a good idea using a mask to try to avoid the sprocket holes ... sometimes ;-)
