         I have been contemplating this exact issue.  Maybe you can offer me
some insight.  I have two M7's now, and my missing link is the inability to
snap both shots at once when the camera spacing needs to be 65mm.  (Due to
the cameras inability to get this close)  I was wondering when shooting
landscapes shots, how critical this is... From what you write above, it
sounds like even the slightest leaf or branch being out of place will play
havoc with ones ability to fuse subjects.  I kind of suspected this, but
have no base for comparison, since I never had the ability to try this both
ways.   Do you find that snapping both shots at once is critical some of the
time, most of time or almost all the time?  Thats what I am trying to get
the feel for....  Any input in this area would be very helpful...

I can probably guess this dual firing is very critical.... if so, what are
some recommendations on newer MF camers that can acheive the critical 65mm
spacing, can be fired siumltaneously and also offer interchangeable lenses?
It seems most of the new box type cameras by Mamiya, Hassy, Rollei, Bronica,
etc. are way to big,  preventing the desired 65mm spacing.

If I were to mount my two M7 80mm lenses on a view camera lens board, they
still will not be 65mm apart, but can get to about 70mm.  Will this extra
5mm spacing ruin the desired effect?  Or would it go un noticed as long as I
am not shooting very close objects, like 3ft.   If this is feasible, I would
consider putting 2 M7 mounts in a Toyo lens board,  focus via the ground
glass, and then insert a 6x12 roll film holder (with a slight bit of
modification) and get two 6x6 chromes.  Of course I would need a light
divider inside the bellows.  I can link the shutters electronically.
I have considered using LF lenses, but they will not get much closer, and
they do not seem as ideal as MF glass since the MTF curves on LF lenses are
not optimized until f16 and higher, while  MF glass is optimized at the
wider and faster apertures... and speed seems a great advantage in MF 3d.

Any holes in my thinking?
