I have access to a 70-200mm Canon IS f4, with a 2x extender (brings it down to f8)
So with the crop factor thats equivalent to 640mm - very nice focal length, the IS is amazing, I was actually doing some fairly smooth handheld work as you'll see in the clip..

This was shot at 640 ISO, f8, at about 10 minutes after sunrise
