	Which RBT ? Several answers were given to that question. Let me add a
few comments, since I gathered some experience from my own RBT camera
and those of many friends.
	My own RBT, a eight-year old double Yashica 108, is no longer
manufactured. It was not always reliable, I had much trouble with the
film progression; now it works, I do not know for how long time.
	I would NEVER buy a stereo camera with autofocus. It is a major
drawback, like as in the RBT S1, in which the autofocus cannot easily be
disabled. It automatically gives pictures being sharp at two meters and
quite fuzzy in the background.
	I would no more buy a stereo camera with zooms, it makes it too hard to
choose the film shift for the window, and you must be permanently
careful to avoid anything in the field, closer than a VARIABLE distance,
depending on the focal distance you choose.
	After buying your RBT, make a film and precisely measure the vertical
deviation. I have already seen X2's with as much as 0.4 mm vertical
deviation (constant on all pictures), I had to recommend the customer to
return this camera back to RBT in order to replace it by another unit.
	Do not buy a 76 mm base RBT camera if you are currently using 1-5/8x4"
slide mounts, there is none for 8 perf slides.
