This is a great camera! I won't try to list out and cover each feature, there's plenty of other places you can read that information. I just want to give a quick note on my take of this excellent camera.
The full frame and high resolution of this camera combined with the Higher ISO settings and greatly reduced noise at the higher ISO settings compared to my previous cameras is outstanding! The Canon 10D is quite noisy when you get 800 or higher. The 30D is much better than the 10D noise wise even at higher ISO settings and when combined with software noise reduction, images can be pretty good. When I compare my 5D Mark II to the 10D, I want to say, "What Noise?!". This that much improved. I have no issue shooting up to 1600 or 3200 for normal shooting. In lower lighting, Going up to the max ISO so I don't need to use a flash and can get decent shutter speeds to hand hold have worked very well.
I honestly haven't used the HD video all that much, I didn't really buy the camera for that, but it's a nice plus if needed.
Bottom line in this camera, the Images are Sharp, the Noise is Low and it's well worth it's price! I do sometimes miss the benefit of the crop factor on my lenses fully zoomed in, but that is easily made up with using the appropriate lens and the ability to crop in much closer than with my previous cameras.
Excellent Camera that I don't regret buying for a second!
