No I didn't do any actual measurements. I know what the 
problem with this image is (excessive deviation between near 
and far points).

I am forced to use a "fixed" setup with the RBT Macro and was 
just wondering if there was anyway to reduce this problem. 
Once again it uses a 105mm lens on a bellows that magnifies 
from approximately 1:3 to 1:1. Inside the bellows is two front 
surface mirrors that "spread" the image from either the 6mm or 
11mm stereobase out to the 65mm interlens spacing of the RBT 
body. Focusing is done by moving the entire unit closer or 
farther from the subject.

Is there anyone out there that can do the math and tell me 
what the maximum near and farpoints are for this setup 
assuming a 1.2mm mofd?

Thanks,
