Being an autofocus camera, it has two autofocus modes, and an option for manual focusing. Its viewfinder is a glass pentaprism. It also has a two-inch, thin-film transistor, color liquid-crystal monitor with approximately 120,000 pixels.
The camera's image sensor is a CMOS-based integrated circuit with Bayer filters for RGB color detection (Canon calls it single-plate, in contrast with three-CCD sensors). It has approximately 11.4 million effective pixels. A non-removable optical anti-aliasing filter is located in front of the image sensor.
The shutter is an electronically controlled focal-plane shutter. Its maximum speed is 1/8,000 of one second. Soft-touch shutter release occurs via an electromagnetic signal.
