This digital SLR camera was developed with the professional user in mind. With its large 8.2 megapixel CMOS sensor and high-performance DIGIC II image processor, the Mark II delivers both superb image quality and rapid 8.5-frames-per-second continuous shooting. Continuing the basic "power" concept of the EOS-1 series, the design expresses "relaxed but powerful speed and acceleration" in the "movement" described by its shape. The camera offers unsurpassed dependability; it can handle the most demanding shooting conditions a pro can throw at it. Its thoroughly splashproof and dustproof construction comes from the lightweight but extremely strong magnesium alloy used for the body's exterior. The design permits full access to all controls, including menu operations, and provides a stable grip for reliable shooting in pressure situations.
