Yipee Skipee!!!! I ordered some other brand battery packs that have more capacity (2200 mAH versus 1300 mAH for original) with it, but I'm sending them back. They work fine, but the fit is horrible. There are gaps in the seams with the batteries cinched in that would let moisture and dust in. Other than that, wonderful. Feels a lot more like the 1V than the original 1D, lightning quick on focus, seems a tad quicker than the 1D in locking focus. Same solid feel, seems lighter than I remember either the 1V or original 1D, excellent finish...etc. All the things that I've come to expect from the 1 series cameras. Now to take it for a test run with the kids. Post some pics when I get some.
