500mm
 
Any thoughts or expierence with a mirror reflex lens? I don't think it would be sharp enough or the right quality for RR photography. I couldn't find many reviews online yet. There is also a F8 version. Cheaper.

Reflex lenses get a lot of their "sharpness" from the relatively long depth of field at f/8, but you're right, they're cheap for a reason. Can you believe that back in the '60s, Nikon made a 1000mm reflex!?

In my opinion, a good telephoto lens with a teleconverter (I use a Canon 1.4x, and a 2x) will get you pretty passable results most of the time, as long as the lens you're putting it on is decent.

I bought the Adorama Pro-Optic 500 f6.3 reflex. It's definitely not for fast moving subjects, but I think it will be fun to play around with.
All of these were shot with a Canon 20D. Haven't tried it on the 40D yet. Images have not been altered other than light sharpening for the resize.

I used to use (and still own) a Tokina F8 500mm mirror lense with a Canon FD mount.

Occasionally I would use if for railway subjects, but its not overly useful as it was so restrictive in terms of shutter speed. I used it more for pictures of birds on the feeders down the garden. IQ was OK, but nothing special
