I have an older C-90 that I bought years ago, and used with a 35mm manual camera. I now have a Canon xTi and bought a T-ring adapter to use with the C-90. The scope is rated 1000mm f/11. While I still am having some issues with focus (but getting better), my main issue is when I look at aperture on the camera it displays "0", and I can't adjust it, thus my pictures tend to be quite dark unless it's a bright day. The hookup is camera, T-ring, scope just as though it were a regular lens. Any thoughts around this?
