I just picked up the 5D2. I think I got a pretty good deal. The seller gave me the receipt which shows he bought it 9/27/11. The camera strap and manuals where never even removed from their plastic, and it is in mint condition. It was a steal at $1900.
Now, should I use it for the shoot (non-paid) that I have Sunday, or should I use the 40D that I am comfortable with???
BTW, is the base iso 200 on the 5d2? It doesn't seem to go lower. I guess I better read the manual

Awesome. That the one on CL? I saw one there for 1900 yesterday or today, but didnt read the description.
ISO goes down to 100 and then down to 50 with ISO expansion. You probably don't have it set to change in 1/3 increments.
