PowerShot A550 [A] [E] [J]
MarketedMarch 2007

Canon's PowerShot A550 incorporates a number of advanced features contributing to outstanding imaging performance, including a High ISO AUTO function, which provides an effective safeguard against camera shake and subject blur by automatically increasing ISO sensitivity to the equivalent of 800. Moreover, the camera effectively utilizes its high-resolution CCD sensor, offering a Safety Zoom function that enables active use of the digital zoom range without compromising image quality, as well as a Digital Tele-Converter function that shifts the angle of view toward the telephoto end by extracting and digitally enlarging the center portion of a captured image.

Equipped with a large 2.0-inch LCD screen (enlarged from 1.8 inches) and a redesigned mode dial featuring five of Canon's most popular Special Scene settings, the new PowerShot A550 offers outstanding operability and ease of use. Furthermore, the camera retains a number of the hallmark design features which the A series is renowned for, including an optical viewfinder and a comfortable, ergonomic handgrip.
