        I bought a second Rollei 35 a few years ago hoping to add it to my
Rollei 35 for a pair.  Mine was a 3.5 and the new one a 2.8, though of the
same focal length and mounted on the same body.  The second was a superb
camera but the lens characteristics were sufficiently different that I
couldn't match it with my old Rollei 35.  Fortunately I found a friend with
the right kind of camera and swapped with him.  He got a great deal on a
beautiful camera and I got a twin camera setup that works extremely well.
The only better solutions would have been to have two of the f2.8 cameras
but that was not in the cards.  

        Point?  A small difference in lenses can render your pairs
unviewable even though the lenses may bear the same focal length.
