I have a 400 f/2.8IS - fantastic on my 5DII. But I bought a 7D for birding - there is no equivalent ff to be had.
Just remember that the 400 on ff is the equivalent to the 250 of APS-C. I dont know how the 1DX people will manage their birding now - it was hard enough on a 1.3 crop.
Perhaps Canon will bring out an EOS 3D - 1.3, 12fps, 16mp, 63point AF - you get the drift. Canon have already said they are not dropping the 1.3 crop ........
