If you needed a 1D Mark IV you wouldn't be asking this question.


Anyways, I suggest you buy the 7D and 5D2. The 7D does 95% of what the 1D4 does for $3000 less. Use that $3000 to buy the 5D2 and you have 2 great bodies -- a great action body and a superb portrait body. BTW, both ARE weather-sealed: I've used my 7D and a friend's 5D2 in snow and heavy rain. No problem.
