Hope that helps mate.
Thanks for all your honest opinions.
I will have a rethink on this.

I've got to agree with that.The 80-400 needs a serious kick up the chuff and upgraded to AFS.
Its far too slow for any kind of action photography.
Maybe if you bird is stuffed and in a glass cabinet it would be ok?![]()
Pat, you may be doing a shoot on a river or lake near to me some time soon.
If you are, give me a shout and I will bring it along for you to have a play.
Or you could always take up my offer of the lake in France.![]()
