Mark,
At first my wife was very unsure. A camera that makes our lenses act shorter, a slower burst rate (Your 1D2 has a nice 8.5fps, our 7D is 7, but the 1Ds2 is a mere 4), lower res, and crappy controls, and a small LCD. What was I thinking?!? She took an ISO 400 picture that showed quite a bit of noise too, and she was ready to tell me to send it back. The USB1.1 1 picture per minute transfer rate didn't impress her much either. Then she saw the results, including some ISO 1600 shots taken in a basement with no windows, and decided that yes, perhaps this camera has found a home after all.
