Canon PowerShot SD850 IS review

Images from the SD850 IS are very impressive. Colors look accurate, there's plenty of sharpness, especially for a compact camera, and at its lowest ISO settings, we saw no appreciable noise. In fact, noise doesn't even begin to encroach until you reach ISO 200. Even then, it's just a very light covering of off-color splotches that's barely visible on computer monitors and won't show up at all in prints. Noise remains similar at ISO 400, with a just-perceptible increase that still won't mar your prints much, if at all. At ISO 800, noise becomes more pronounced, robbing some finer image detail, and adding filmlike grain to prints. Surprisingly, while darker colors become washed out at this point, there's still a fair amount of shadow detail. At its highest sensitivity setting of ISO 1,600, most finer detail is obliterated by noise, and lots of shadow detail is lost. Rather than a fine grain, the noise becomes larger and causes a nasty blotchy look overall. We recommend staying below ISO 1,600 if you plan on making prints and below ISO 800 if you plan to make prints larger than 8x10 inches.

There's very little to complain about on the SD850 IS. Fans of ultracompacts, such as Sony's T-series, might complain that this Canon isn't small enough, but given its excellent image quality and speedy performance, I'm not complaining. Also, unlike those Sony cameras, this one includes an optical viewfinder, for situations, such as concerts, in which an LCD might annoy those around you. Bargain hunters will likely balk at this camera's price, but again, its features and performance make it worth the premium over a bargain-basement camera.
