@jo13 Just deleted your comment by mistake! Not even had a glass of wine yet! Thanks for thinking of me. I am afraid it will have to be a no. I can't really justify the money at the moment. I haven't tried the f4 yet tho I am thinking of swapping the f2.8 I have hired for a wedding I am taking photos at in a couple of weeks for the f4 mainly because of the weight and the fact that I can't see myself having the f2.8 wide open because the dof is soooo shallow. Sure you wont have any probs selling your lens. Jx
