1D 2. It has a very solid, well built feel that I have not experienced before and the kind of weight you would expect from a high quality product. I have to say that the first thing I noticed that really impressed me is the quality of images taken at high ISO. Even at its highest ISO of 3200, the noise that is present has a quality that beats a picture taken at 400 ISO from my Pentax. The noise produced by the 1D 2 gives the images a really classic feel and I like that a lot. Pixel peepers may be cynical about all the technicalities but the difference between a great photograph and a snapshot is its substance.
