Are DSLR cameras good for video?

Yes, the great majority of professional cinematographers agree that Canon’s cameras are great for video, and a few have gone so far as to say that Canon DSLRs are more than just about as awesome as film cameras:

And in our video test, we had several people who used a Canon Rebel XT or C300 video setup tell us they used video to make the Final Cut Pro 10 video that won a Best of Crop contest for a competition that was sponsored by Canon-brand cameras and equipment manufacturer, Kowa.

Video has been an important part of how film cameras work for years. It has been very important since the beginning of computer-based film production and film editing. However, the new trend in video and digital is showing that video has a way of being used in ways that are not really traditional film – the more so in the case of digital. And most stills, which have to have the image in the same focus as the motion, often have the image in a focus point (like the side of the subject) rather than the center of the scene. This is sometimes called “focus peaking” or “focal peaking.”

Many still photographers have a love/hate relationship with these peakers. Personally, I love them – I just don’t see them as important unless they are used on a video system. Most still cameras, especially Canon ones, have a lens aperture setting that can be set to compensate for these focus peakers. And in some of the higher-end video cameras, such as the Canon EOS 60D or the Canon EOS 60D Mark II, the lenses are designed in such a way that a camera (such as a 60D) can be mounted in a way that provides the needed resolution without any focus peaking.

But my personal favorite method of keeping the shutter open longer (or even longer – depending on the camera) to capture video is not usually with a camera but with a tripod:

I have seen many a video of athletes doing gymnastic moves with the camera held at the right height to capture the movements well enough to show them in motion. With that camera mounted on a tripod, I usually have no trouble standing back up again. Now, that’s not to say that a single, high-end camera can make that happen, though. For some of the more expensive and high-end video cameras you will need some sort of support that will hold the camera steady. And some companies will make video rigs that
