The Canon PowerShot SD40 follows the SD30 by adding a few more megapixels, a whole new image processor, and a few adjustments to the specs. This 7.1-megapixel Digital Elph comes in four trendy colors and measures smaller than most cell phones. It has a 2.4x optical zoom lens and a 1.8-inch LCD screen. The biggest innovation on the SD40 is the Digic III image processor that touts face detection and noise reduction technology. In September 2006, Canon announced the SD40 along with two other PowerShot cameras. The company claims that its newer Digital Elphs, including the SD40, are designed to be a little more upscale than previous models. The Canon PowerShot SD40 looks to be just that with its stainless steel housing and trendy styling. The digital camera retails for $349.
