The 50.6 megapixel full frame CMOS sensor is capable of recording extraordinary levels of detail. The ultra-high resolution enables extensive cropping and still delivers stunning image quality. Even the built in 1.3x and 1.6x cropped shooting modes produce 30.5 and 19.6 megapixel files, respectively. EOS Intelligent Tracking and Recognition (iTR) AF technology uses colour and face information to recognise and track subjects as they move around the frame. AF responsiveness can be customised using a simple tool, which adjusts the focus tracking according to the shooting environment and subject, so that other objects passing momentarily in front of the subject don’t interfere with focusing.
