The race to cram ever more processing power into digital cameras has its advantages. Namely, when companies like Canon introduce cameras such as the SD-300, which can snap shots at four megapixels for an affordable price, consumers win. However, there is a downside to all this processing power. Sometimes, companies try to hype cameras by bragging about their resolutions without explaining that great resolutions don't mean better image quality.

Let's examine a case in point, the Canon PowerShot SD-400. Although it's considered an upgrade of its sister model, the Canon PowerShot SD-300, the only real difference between these two cameras is the price and a bump in resolution. Whereas the SD-300 provides four megapixels, the SD-400 provides five megapixels. An extra megapixel may sound like a pretty good deal for a few extra dollars, but the fact is that the sensor employed on the SD-400 is simply not up to the task of handling so much information.

As a result, when you take photographs with the SD-400, they have a tendency to blur--even more so than the photos taken by the smaller SD-300. While this blurring doesn't occur in all shots, and the SD-400 comes equipped with a number of exciting features, such as a cool movie mode, the Canon's lovely DIGIC image processor, and good battery life, you should consider alternatives.
