In P3D 2053 Sam Smith replies to my question (same post):
>I think what you are saying is that you have a conventional stereo camera
>which you have attached "auxiliary" telephoto lenses to. Correct? 
 That IS correct.
>If so, these attachments do vignette far more than the wide angle ones.
Yes, this is the problem that I'm experiencing.
 >Exactly how far away is the first optic from the outside camera optic, and 
>how are you attaching them?
I'm using one step up ring. There is probably 3 to 4mm between the lenses.
Again, what I'm asking is, will larger telephoto lenses (49mm) solve the 
vignetting problem? Any Idea? Any experiences?
Thanks again,
Bruce M Rosenberger
