Click to take a QTVR tour of the SD40

The fashion plate of Canon's Digital ELPH line, the PowerShot SD40 packs 7.1 megapixels of resolution into a
color-keyed, durable stainless steel body. Not only is it stylish, but fun and easy to use. From the virtuosity of its 7.1 megapixel CCD and 2.4x
optical zoom lens (38-90 mm equivalent) to its easy-to-read 1.8-inch backlit LCD monitor with 15 brightness
settings the SD40 Digital ELPH camera is Canon to the core.

Similar in design to its 5.0 megapixel predecessor (the SD30), this
new Digital ELPH model offers four new stylish shell tones to choose from: Twilight Sepia, Precious Rose, Noble, and Olive

Canon also supplied the SD40 with an easy to use camera station that serves as a charger,
High-Speed USB 2.0 for direct printing and image transfer to a PC, and the supplied
wireless remote lets you display slide shows when sharing images on a television screen.
At a mere 0.94-inches thick with the lens retracted, 1.78-inches high and 3.78 inches long,
and a body weight of just 3.7 ounces, this camera can be carried or tucked away anywhere.

Thanks to the DIGIC III chip's more aggressive noise reduction, this model is able to shoot at
ISO equivalent speed ratings from 80 to as high as 1600. This increased sensitivity at the top-end allows the
use of faster shutter speeds, significantly reducing camera shake and subject blur during hand held low-light

Canon's new Face Detection AF/AE technology (working in concert with the SD40's 9-point
Autofocus system), allows it to detect, lock on and track up to nine human faces in a
scene simply by pressing the shutter button halfway. The face detection algorithm
automatically prioritizes and selects the optimum subject and not simply the closest face
(based on Canon's Intelligent Scene Analysis/iSAPS technology). It will then optimize the
focus and exposure to ensure the best possible results for easy picture taking moments.
