I don't see bigger and heavier as a "feature." If a camera has to
weigh that much, give me a D2X - something actually designed to be
held.
Well if I decide to pay 4400 dollars for a D2X, I know I'm getting
the exact same body as my D2H. I can work around the higher noise.
If I pay 3300 dollars for a 5D, I'm getting an unknown quality and
having scene the fiasco with the horrible 10D autofocus, do you
really want to pay this much money on an unknown Canon prosumer
body?
But the one reason I wouldn't buy a D2X right now is the fact that
it seems like a prototype. My gut feeling teels me they're going to
introduce an updated version with better noise control.
