A review of the Canon PowerShot SD630 has been done by Imaging Resource where they write, 'The Canon PowerShot SD630's performance is pretty good overall, starting with its fairly quick startup time of 1.3 seconds. Shutter lag is good at wide angle and telephoto, with a quick "prefocus" time of 0.074 second. ("Prefocus" means half-pressing and holding down the shutter button before the final exposure.) Shot to shot cycle times are a little better than average, at about 1.62 seconds for large/fine JPEGs, averaged over about 20 shots. Continuous-mode speed is slightly slower, at a bit over two frames/second, for 20 shots or more. The flash takes about five seconds to recharge after a full-power shot, about average for this class of camera. Connected to a computer, download speeds are very fast. Bottom line, the SD630 is a good overall camera, with quick response under most normal conditions, despite a slightly limited continuous mode.'
