Thanks all
Glass eye - we were probably around 15-20 metres away from the bird, which was up a tree....... I love this lens, but have no idea on what to use for surf photos.... maybe post a question on the forum, because I know there are others in here that take brilliant surf photos!!! If you do get this lens, be aware that you can't use the 1.7TC with all of the versions .... I have the old AFS ED version which allows me to use the 1.7. Good luck
