Usually, DSLR’s only shoot still images. But recently, they’ve started shooting videos too. The Canon 5D Mark II is so far the best – it shoots HD video, with full color and exposure control, and it lets you zoom and focus while shooting. It’s so good, in fact, that independent filmmakers are using it to shoot films.
The only problem, though, is that the audio is weak. It only has one input, so if you want high quality or surround audio, you have to use a separate audio recording system. Plus, it’s a very expensive camera.
It’s tempting to buy one right now, just because the idea of having two in one is so much fun. But the quality of the recording isn’t good enough yet. This is still a brand new medium, and it needs to improve a little bit first. It’s still in its “beta” stage. Sometimes it is better to wait for a new gadget to improve than to buy it when it’s brand new. Otherwise, you get stuck spending a lot of money before you get the item you really want.
