Canon C300 Mark III

Impressive usability and imaging power combine in the EOS C300 Mark III, a customizable cinema camera that’s built for versatility and flexibility.
The lightweight body features Canon’s Super 35mm Dual Gain Output (DGO) Sensor capable of over 16 stops of dynamic range. The DGO Sensor is an imaging system that generates high dynamic range and maintains low noise levels by reading out each photodiode with two different gains. It combines the two with saturation prioritizing gain for bright areas, and a lower noise prioritizing gain for darker areas.
Also at work here is the DIGIC DV 7 Image Processor, which expands functionality and flexibility by enabling features such as internal RAW recording and Dual Pixel Autofocus. Additionally, Frame rates up to 120 fps can be obtained in 4K, while 2K CROP mode provides even greater flexibility with speeds up to 180 fps. With this processor, the EOS C300 Mark III can record Cinema RAW Light directly to onboard CFexpress™ cards. Cinema RAW Light offers plenty of freedom for grading with a dynamic range that can exceed 16 stops, while maintaining file sizes that are about 1/5 to 1/3 the size of Canon Cinema RAW. Canon Cinema RAW Light offers a great combination of codec efficiency and quality.
The EOS C300 Mark III Digital Cinema Camera incorporates the new Canon XF-AVC codec that allows 4K and 2K image data to be recorded internally onto CFexpress™ cards in workflow-efficient file sizes using advanced video compression. Using the XF-AVC codec, the EOS C300 Mark III can record a variety of frame fates up to 4K 120p and 2K up to 180p.
The camera supports both Canon Log 2 and Canon Log 3 Gamma. Users can upload and apply custom LUTs to the camera. LUTs can be assigned to specific output terminals, the LCD and the viewfinder. Clients can be viewing one LUT while production works from another, giving different production roles the ability to customize the look of the image to their needs. Go ahead and record the XF-AVC 2K 4:2:0 8-bit Proxy directly to an internal SD card with LUTs applied!
The EOS C300 Mark III is available with either an EF or a PL lens mount and supports the use of both 2.0 and 1.33 anamorphic lens types.
It includes the same built-in five-axis electronic IS introduced with the EOS C500 Mark II that works with almost any lens, including anamorphics. It also features Canon’s excellent Dual Pixel CMOS AF technology.
It comes with the LM-V2 4.3″ LCD Monitor, an easy-to-view touch panel with approximately 2.76 million dots, capable of displaying both image framing and visual confirmation of camera settings. Additionally, it has a control interface to make it easy to access and change camera settings.
