The Canon EOS C300 mark III is a Super 4K camcorder for broadcasters and documentary filmmakers. In addition, it allows corporate video productions to capture creative visions with impressive cinematic quality.

The Canon C300 mark III with Dual Pixel CMOS AF has a Super 35 mm CMOS sensor. This makes autofocus faster and more precise. The EF lens mount offers compatibility not only with Canon's wide range of DSLR lenses, but also with EF-mount cinema prime and zoom lenses. The Super 35 mm sensor is combined with the Canon DIGIC DV7 image processor, which applies an innovative method to improve color reproduction.

The camera records 4K video to a single CF-Express card using the XF-AVC codec and MXF wrapper in H.264 format. For greater flexibility in adjusting shots during post-production, the camera also offers Canon Log Gamma mode, which results in excellent tonal reproduction in highlight and shadow areas of an image and an extended dynamic range.

The camcorder features a 12G-SDI output, timecode I/O, and Genlock input BNC. The body has a modular design that can be built using optional accessories. The EOS C300 mark III can be expanded with the EVF-V50 OLED electronic viewfinder, the LM-V2 LCD monitor, and many other accessories.

The Dual Pixel CMOS AF upgrade uses the existing Super 35 mm sensor in the Canon EOS C300 mark III. Dual Pixel CMOS AF is a sensor-based phase-detection AF technology to support video recording. The technology has been adapted to the cinema camera's capabilities and is optimized for fast and natural focusing. Focusing on moving subjects is simple and easy.
