Photo and movie quality rank high for an ultracompact. In fact, despite almost identical innards with the SD1000--they both use the same sensor, f /2.8-4.9 35mm-105mm (35mm equivalent) 3X zoom lens, and Digic III processor--the photos from the SD750 look a bit better, especially vis-a-vis high ISO noise. As measured by CNET Labs' tests and in photo samples, the SD750's noise profile generally outperformed both the SD1000 and the SD800 IS. With the exception of photos shot under our extremely warm tungsten lights, white balance, exposure, and saturation look very good. Movies look equally good, in part because Canon captures in MJPEG, which uses far less compression than other cameras' MPEG-2 or MPEG-4 formats. As a result, a 30fps 640x480 movie uses about 2MB per second of storage.
On the other hand, the SD750's performance matched that of the SD1000. It takes 1.0 second from start to shoot, with subsequent photos about 1.6 seconds apart without flash and 2.3 seconds with the flash enabled. Shutter lag measures 0.5 second in our high-contrast test, which mimics bright shooting conditions, and 0.9 second in our low-contrast test, which mimics dim shooting conditions. Continuous shooting was the only disappointment--approximately 1.6 frames per second regardless of image size.
It lacks the image stabilization of the SD800 IS and the tiny appeal of the SD1000, but the Canon PowerShot SD750 has a more elegant, cutting-edge design, large LCD and--to my eyes, at least--better photo quality.
