Sandwiched between similar 7-megapixel siblings--the PowerShot SD800 IS on one side and the PowerShot SD1000 on the other--the Canon PowerShot SD750 nevertheless manages to distinguish itself as a well-designed, practical option for snapshooters who favor big LCDs over optical viewfinders.
The 5.3-ounce SD750 doesn't quite match the SD1000 for compactness, but its 3.6x2.2x0.8 inch body will fit just as comfortably in a pants pocket. It comes in silver and silver with black accents, the latter design recalling the early film Elphs. The Touch Dial Control--so named for its optional ability to display a virtual dial when you simply touch the control--quickly accesses the small set of shooting options, including ISO speed, flash mode, macro/infinite focus, and continuous/timer. Though it doesn't offer manual or semi-manual exposure modes, it does supply a host of color enhancements and scene modes, exposure compensation, and a choice of three metering modes.
For focus, Canon provides a face-detection AF mode, which automatically locates a face (just one) and determines focus and metering for it. That's in addition to the company's standard AiAF automatic focus-point selector and center focus. The face-detect AF works reasonably well, but the option is buried within the menus and only works in conjunction with the AiAF; that is, if it doesn't find a face, it falls back on AiAF. I generally don't like the automatic focus selection on any camera--they never seem to find the desired subject, just the closest. So I don't like the face-detection option stuck in a set-it-and-forget-it location. You may feel otherwise.
Overall, however, I find the SD750's layout intelligent and comfortable to use. It has a big 3-inch LCD for framing and playback. The LCD appears bright and easy to see, even in direct sunlight, although it also tends to look a bit coarse.
