Finally a review that might stop people switching in droves. The first positive I've read about the 1d MK4.

FWIW, I keep switching between the relatively cheap upgrade to a 5dmkII or the expensive upgrade to a d700. AF vs pixels. Dreamy noise vs cropability. CLS vs Canon ETTL. If Canon didn't have such a lovely range of portrait primes (100mm f2.8L/ 135mmL) this would be much easier.
