Hmm. You've got me wondering again whether the 5DII is the right camera for my interests - after the mass bemusement in a thread suggesting I swap a while ago I shelved the idea but I'm really not that interested in landscape photography. The AF points and extra reach would really be a big boon. But then again shots that I do manage to take on the 5DII with the 400mm - assuming I can get close enough and assuming the AF points don't let me down - promise to be stunning.
