Canon EOS-1D X Mark III is a powerful DSLR designed for sports, wildlife, and other trying and dynamic imaging applications. Designed as the flagship of the EOS system, the 1D X Mark III is characterized by its refined processing capabilities and distinct speed to suit both photo and video applications. Featuring a newly designed 20.1MP full-frame CMOS sensor and updated DIGIC X image processor, this camera is capable of continuous shooting rates up to 16 fps with the optical viewfinder or 20 fps in live view, with a 1000-shot buffer when shooting raw+JPEG. Complementing this speed is an impressive native sensitivity range from ISO 100-102400, that can be expanded to ISO 50-819200, to suit working in a variety of lighting conditions. Also benefitting the speed is the EOS iTR AF X autofocus system, which uses 191 points for quickly and accurately acquiring focus. It also enables Face Tracking and Head Detection AF functions, which use Deep Learning Technology, to maintain critical focus on moving subjects. Additionally, when working in live view, Dual Pixel CMOS AF uses 3869 manually selectable points and provides a smooth, natural focusing quality akin to the way a camcorder acquires focus.
