How long is in fact 500mm lens used on 20D? It is very, very difficult to manage that length without a tripod or at least mono pod and you don't mention it in the data!

Hi Pierre

This was taken with the aid of a Gitzo tripod, Markins ball head and Wimberley side kick. Have just added details to equipment.

35mm equivalent I think goes something like this on a 20D (30D or 40D).

500mm *1.4 (for the converter/extender)*1.6 (crop factor of camera) = 1,120mm equivalent focal length

However the camera data says its just over 1,200mm, from memory, and I can never work that out :-).
