The video feature of current DSLR cameras is interesting. Several things to note:

1. The quality of the video is pretty good. It eats up HUGE amounts of card space.

2. The feature set of the DSLR versus a small HD video camera is quite different. No (or very poor) autofocus during video shooting, for example.

3. The very large sensor in the DSLR is getting a lot of attention from filmmakers, because it's ten times the size of the sensor in an HD video camera. That's great for controlling depth of field, but it means that focusing the camera becomes much more difficult.

4. Make sure the lens has an Image Stabilizer, or use a solid tripod. Again, most vidcams have some sort of stabilization. The Canon bodies don't -- you need to buy it in the lens.

5. Not all video editing programs can handle the video codec from the DSLR cameras without converting it to something else.

It's nice to think I could carry one camera that would do it all. Not sure that's true yet.
