Looking at the Canon Digital IXUS 750's performance scores, it's clear that the company's Digic II processor has a lot to offer, though there's also room for improvement. The IXUS 750 remains one of the champions of point-and-shoot-camera start-up time, going from power-on to first shot in a mere 1.6 seconds. It also posted some decent scores in the shutter-lag department, logging a delay of 0.7 seconds under optimal light and 0.8 seconds under dim conditions. With the flash disabled, shot-to-shot times averaged a little less than 2 seconds, placing it in the top third of compact snapshot cameras; enabling the flash slowed things down significantly, upping the time to a more middling 3.4 seconds. The camera's burst mode captured 10 full-resolution shots before flagging at a pace of 2fps, while dropping the resolution and upping the compression increased the number of shots we could snap to somewhere beyond 50 but slowed down to 1.8fps.
The IXUS 750's proprietary lithium-ion battery performed very well, giving the camera enough power to get through nearly 1,300 shots before it sputtered and died. There are six stops along the camera's 3x optical-zoom range; since there's no onscreen indicator of where you are along the continuum, you'll either have to guess or zoom all the way out to orient yourself. Zooming action is a bit noisy, but unless you're engaging in some serious covert ops, the sound won't impede the camera's overall functionality.
