Thanks Julio, I have had this lens for four years now so I have had planty of practice! This shot was a quick hand held snap when it flew from a tree as I approached, it saw me before I saw it. Those with longer lenses (and I have just got one) would have had difficulty getting any shot away in this situation. Dave.
Nice eagle pictures and very good technique. As an owner of a 80-400mm I can attest that it is not easy to get birds in flight with this lens. Congrats!
