Thanks guys. I'm not sure how much my wife will let me play with it (she considers it hers already) but I'm certainly looking forward to giving it a run
I'm very happy with the price - and best of all, it's a local pickup and it turns out I know the person who's selling it (the wife of a friend of my brothers). Small world!
I've got an 85mm 1.8 on loan from a generous IIS member so can't wait to give it a try later today when I pick up the 5D.
PS: Still on the lookout for a second 5D Mk 2 so I've got 2 FF cameras when out shooting nightscapes
