In 2 years, the 1Ds III will STILL be an amazing camera. The other options out there don't change the fact that it has a great AF, great IQ, and all around great feeling.
It's worth every penny -- especially as cameras with video capabilities start to dominate the market. If you don't need that, buy 2 of them!
They also don't change the fact that it's 7000 euros. And if I'm being paid 100 euros a shoot, how many years would it take for me to save enough money for one?
Used in the UK they are now about 2000 euros - about the same prince as a new 5DII, and you get a better camera if high iso is not an issue
