My main reason for telephoto lenses on a stereo camera are for 
the opposite effect: close-up images. Using a telephoto lens 
allows you to be farther away from your subject while 
maintaining the same on-film magnification. This helps keep 
the parallax down to a tolerable level when using a wide 
stereo base. Of course all others rules still apply - like 
limiting total scene depth.

In my case I am using 28-70mm zooms on a 65mm base RBT. I zoom 
out to 70mm and turn down to minimum focus. This has worked 
well and produced many images that have been accepted in 
exhibitions (even one that won best new exhibitor at 
Hollywood).

And just to tie this into the original thread - I have owned 
several Realist cameras and have nothing but praise for them 
as well.

That's all for now,
