Comments about Sigma 170-500mm APO F5-6.3 DG AF Zoom Lens for Canon EF:

Shooting birds of prey in different terrains, I have found this lens a real tough guy. I was warned by the salesmen that auto does work but not very well. That is an understatement, I found that in auto it is impossible to focus. Manual focus if fairly smooth for a lens that is half the cost of Cannon. Yes it is also slower (f 5.6) but in nature your best shots are often bright sun light. Though you can hand hold it, I would not, I have been using it on a tripod and it works fine.
