Hi Dan,

Though I have never seen or used these expensive cameras or even the Fuji, Linhof, etc. I do know that the standard focal length for use of 617 cameras has been the 90mm focal length. I would certainly think that for most applications that the 90mm would be preferred. The image size and the angle of view for the 72mm would get substantially smaller, less useful, and I would guess considerably more difficult to control.
