Out of interest, whist thinking about some future possibilities, does anyone know how easy it is to share one's large format lenses between a standard lf camera and the various more compact shift option cameras such as alpas, fotoman dmax, or upcoming arca r which all use a helical focussing system?

I'm wondering as there are various occassions when you need / want to have shift and rise movements but need a hand holdable camera such as the ones above..and of course don't want to invest in 2 sets of lenses.

I am not talking about changing lenses between the cameras in the field or on location but in the studio.

Cheers,

Marc
