Canon also announced a new DVD camcorder that has an interesting feature. The $699 DC22 is a nicely designed, small camcorder that Canon claims is the world's smallest. The new model (which will be available later this month) can write to the new 8cm DVD-R dual-layer discs, which hold 2.6GB of data--double the 1.3GB capacity of their single-layer cousins.
This greater disc capacity goes some way toward alleviating one of my major complaints about current DVD camcorders: You end up swapping discs every few minutes. The DC22 can store 36 minutes of video at the highest quality on a dual-layer disc, up from 20 minutes on a single-layer disc. But while that capacity is an improvement, it's still not as good as that of a MiniDV camcorder (which can hold 60 minutes) or the new breed of hard-drive camcorders, which can hold many hours of video. The new dual-layer 8cm discs are expensive, as well: about $20 for a pack of three. For that price, you can buy a pack of 20 single-layer discs.
This certainly won't be the last camcorder to use the new higher-capacity discs: I expect that the next generation of Sony DVD camcorders will also support dual-layer discs. The recently announced HDR-UX1 can write to DVD+R dual-layer discs, and Sony will probably use the same DVD mechanism in its next generation of standard-definition DVD camcorders. But right now, Canon is the only manufacturer offering this extra recording capacity in a DVD camcorder.
