It's a great camera for stills. But if you have the funds the Canon EOS 7D is a significantly better camera. This will run you $1800 w/ lens.
I completely agree with Motegi. I just bought the Canon 7D about 4 months ago and I am taking pictures that look Pro - I can't believe it! I chose the 7D because it is the first pro-sumer camera that has the speed and 1080p video capabilities that I wanted and image stabilization. The Video capability is very handy, and I can do great depth-of-field tricks with my lens that could previously only be done with $50-$100K professional video cameras.
I bought this lens and didn't waste my $ on a kit lens with poor speed and image quality. this lens is AWESOME for speed and clarity. I bought the body without a lens and a really good UV filter for this baby. It isn't very heavy, has really crisp optics, and the f 2.8 gives me GREAT depth of field and flexibility for indoor/outdoor.

My next lens will be a nice 35mm prime with a 1.4 aperture. Canon is coming out with some different EF-S primes later this year and I am waiting. I think every photographer should have a 50mm prime with wide aperture. the 35mm size translates to just about a 50mm with the 7Ds cropped image sensor (1.6x factor).
I think if I win the lottery, I will be getting the 70-200mm f2.8 "L" series. I do night shots with some action photographing our high-school band. Wife won't let that purchase go unnoticed, so it is on my santa clause list.
oh yea - storage cards. I got the 60mb/sec 16GB cards to keep up with the video saving. I would probably switch to 32GB if I had a chance if you do Video.
one more pointer... START shooting RAW from the beginning and use Canon's tools to do the editing/workflow. I started shooting JPG for about 2-3 days until I figured our I could adjust all my photos in RAW lossless and create JPGs later - that way I have ultimate control over white balance, color, etc... without sacrificing image quality doing adjustments in Photoshop.
Good Luck !
