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.

Battery and Storage Capacity

Short battery life.

Test Conditions
Number of Shots
LiIon rechargeable battery

The Canon PowerShot SD630 uses a custom rechargeable LiIon battery for power. The table above shows the number of shots the camera is capable of, based on CIPA battery-life and/or manufacturer standard test conditions. Given the short run time, you should definitely consider purchasing a second battery to pack along on extended outings.

A 16MB SD card is included with the Canon PowerShot SD630.

I strongly recommend buying at least a 256MB card, preferably a 512MB or higher one, to give yourself extra space for extended outings.
