The Canon SD630 brings Canon's ultra-compact cameras into the big leagues with a huge, 3.0 inch LCD screen. More and more it seems like we're reaching the point of equilibrium with digital cameras, where the camera has reached its smallest size and the LCD screen has reached its largest. Looking ahead, we at DCHQ don't see how it can get much better than this. The Canon SD630 has that extra half-inch over the similar SD600, otherwise they're virtually identical: 6 megapixels, 3x optical zoom, pretty good stats for a mainstream ultra-compact camera. Throw in the high ISO settings, and you've got a strong camera with some really neat new features. In fact, it's so confident in the power of its LCD screen, it's completely done away with the optical viewfinder, a first for Canon's teeny tiny line.
