18.0-megapixel CMOS sensor and Dual DIGIC 4 image processors
The EOS 7D features a Canon-designed 18.0-megapixel APS-C size CMOS sensor that captures such a high level of resolution it’s easy to crop images for enlargement without concern of losing detail. A major factor in reducing noise, the CMOS sensor assures that images shot at highest sensitivity will be remarkably smooth. Dual DIGIC 4 Image Processors ensure that images are captured, processed and saved with remarkable speed. The EOS 7D’s ability to capture and process data of images shot at 18.0 Megapixels at 8 fps, as well as Face Detection Live Mode, Full HD video recording, Auto Lighting Optimizer and Lens Peripheral optimization are all possible thanks to the Dual DIGIC 4 Image Processors.

ISO 100-6400 (expandable to 12,800) for shooting from bright to dim light
With a broad range of ISO settings, the EOS 7D enables shooting from dawn through dusk and ensures capture of the finest detail. With enhanced, low-noise high-sensitivity optimization, shooting in situations previously possible only with flash becomes as simple as point and shoot.

8.0fps continuous shooting up to 126 Large/JPEGs with UDMA CF card and 15 RAW
Capable of shooting up to 126 Large/JPEGs with a UDMA CF card and 15 RAW at 8 fps, the EOS 7D is a perfect camera for action. Canon’s remarkable shutter, combined with speedy, sophisticated electronics, ensures instant response and performance. A rapidly-occurring scene can be captured moment by moment, second by second, so that even the briefest of opportunities are captured in perfect clarity.
