Hi thanks for the replies.

Apart from liking to take close up pictures of flowers and small bugs etc which i know i need a good macro lens for i find my self wanting extra zoom.

for example, on holiday you could walk a long the beach and the planes would come in to land right by where you were walking, i found my self wishing i had more zoom to try and get close shots, there were different types of small birds feeding from the rock pools but get to close and they would run off, again i wanted more zoom.

I took some pictures of a small bird trying to catch small fish (posted below) but sometimes they were to far away to get a good shot, if only i had more zoom!
