Canon PowerShot S3 IS

The Canon PowerShot S3 IS's aesthetic seems to be a cross between those of a classic Volkswagen Beetle and a Busy Box. Granted, it's the same body as its predecessor's, but the silver bits stand out more against the current version's iridescent, dark gray plastic than they did against the previous model's silver coloring. As with the S2, there's certainly enough here to keep you busy for a long time, though, and loving every minute of it. (For more details about the S2/S3's basic design and features, read the PowerShot S2 IS review.)

For the S3, Canon upped the size of the flip-and-twist LCD to 2 inches from 1.8, which is still disappointingly small. The company also added a ludicrous 16:9 aspect mode: not only does it simply crop and letterbox the standard 4:3 image, but the LCD is too small for a functional letterbox display. More useful is the new 320x240 60fps movie-capture mode, which produces slick little movies, as does the VGA, 30fps mode. Unfortunately, the camera still lacks raw format support.

Oddly, despite the different sensors--or perhaps because they use the same f/2.7-to-f/3.5, 36mm-to-432mm lens and Digic II imaging processor--the S3's photos look almost identical to the S2's. They display a broad tonal range, albeit with some clipping in the highlights and shadows, very good color accuracy and saturation, and acceptable edge-to-edge sharpness. Its noise profile follows suit as well: low until about ISO 200, then increasingly bad. Though the camera can now boost ISO sensitivity to as high as ISO 800, either manually or by enabling ISO Boost in a programmed-exposure mode, the noise at that setting is quite obtrusive. In general, the S3's photos look good but can't really shake the digital look, either onscreen or in print.

Performance, while not identical to the S2's, is either the equivalent or better. Start-up to first shot takes only 1.5 seconds, which is quite zippy overall, and extremely good for a camera that has a long lens to extend. Shutter lag in bright light runs about 0.4 second and doubles to 0.8 second when the lights get low. The S3 is also relatively responsive: 1.1 seconds typically from shot to shot, plus another second if the flash needs to recycle. Though it maxes out at 1.5fps in continuous-shooting mode, there's no buffer-constraint on the number of sequential shots at maximum resolution; I find that much more useful than a fast but limited burst mode. It was certainly sufficient to capture active dogs and children playing in the park, including kids spinning in a tire swing.
