Hi,
if you need wide-angle a want to do some studio, have a look a the Silvestri Flexicam. I posted pictures in a thread here. You're limited to 105mm officially (i suppose with Copal lenses) but i used my Hassy V-system 120mm (via adaptor)with succes for tabletop. For the moment i sue the 60,80,120mm Hassy lenses only, i tested and ordered the Digitar 35, a 100mm digitar will come later.
You need to order a sliding back specifially for each mount (no insert like P1 flexadaptor).
Some of the pancake cameras offer tilt possibility (Arca?), I don't think it's enough for studio work
