Yeah TIm, I was following Pixmantra's posts on the other forum and I agree with what he sees and says. The D3s still edges out Canon, but I will have no use for ISO's that high. And personally, I will take some noise over smudged details any day of the week. Clean 6400 is all I would ever need. I venture into 3200 only occasionally anyways. I am so excited to finally have a 1D, I can hardly wait. I think that paired with my 5DII, it'll be a fantastic combo. I see your gear is very similar to mine. LOL
