Thanks for the compliments on the photos. It makes it just that bit more rewarding when you know that the pics are being enjoyed. beebee, i am using mostly a 70 - 200 f2.8 for the photos that you see, but i have also done a few close ups with a 400mm f2.8. Problem is it's like pruning a rose bush with a chain saw ( bit to big for the fine stuff ). An animal of a thing to use close up when you guys are darting all over the place.
