The Canon PowerShot A640 was introduced this fall as a 10-megapixel prospect for the holiday season. It replaces the 7.1-megapixel Canon A620 and is the first A-series camera to include a whopping 10 megapixels. The PowerShot A640 has a Digic II image processor, a 4x optical zoom lens, and 21 shooting modes with a range of manual and automatic modes. The A640 also has a 2.5-inch LCD screen that flips out from the camera body and rotates. It adds interesting features like a digital tele-converter and tethered remote shooting – items that are fairly new to the PowerShot line. The Canon A640 retails for $399 and can be easily found for about fifty dollars less online.
