Canon EOS C300 Mark III
The next generation EOS C300 Mark III incorporates Canon’s newly developed 4K Super 35mm DGO sensor, with 4K 120P Slow motion, High Dynamic Range and Dual Pixel CMOS AF into the same body as the EOS C500 Mark II.
New 4K Super 35mm CMOS sensor for breath-taking image quality
Equipped with a newly developed 4K Super 35mm DGO sensor and DIGIC DV7 image processor, the EOS C300 Mark III delivers an exceptional high-resolution image with 16+ stops of latitude.
It also has an impressive low light capability, with improved low noise, of up to ISO 102,400 where the human eye cannot easily see.
Super 35mm DGO (Dual Gain Output) Sensor generates HDR in real time
The DGO sensor is a newly-developed imaging system that offers exceptionally clean low light image quality as well as superb HDR acquisition capabilities.
On the DGO sensor, each pixel will read out the image with two different amplification levels, one high and one low, which will then be combined to make a single image. The higher amplification read-out is optimized to capture clean details in darker areas, while the lower amplification read-out is optimized to capture the details in brighter areas. Hence, when combined together at pixel-level accuracy, the details and the qualities on both the highlight, as well as the low light areas will be maintained and enhanced which enables the camera to achieve an impressive higher dynamic range of up to 16+ stops.
The new DGO sensor is also compatible with Dual Pixel AF giving the user greater freedom to achieve the image they desire.
High frame rates up to 120fps in 4K
The EOS C300 Mark III supports continuous 4K recording at up to 120fps, in both Cinema RAW Light and XF-AVC. In 2K (crop) mode, frame rates from 12 fps up to 180 fps can also be set for greater creative freedom, while a dedicated Slow & Fast button, provides quick access to the desired Slow & Fast setting.
Dual Pixel Focus Guide
Dual Pixel CMOS AF phase-difference technology provides an innovative graphical guide that represents front/back focus deviation; the rectangle turns green when the subject is in focus, improving usability and accuracy when manual focus pulling, especially for critical focusing in 4K.
Simply use the touchscreen to select an object in the frame and it will be tracked as it moves within it, enabling effortless subject tracking, taking all the hard work away.
Face Priority AF / Face Only AF
Working together with Canon Face Detection technology, Dual Pixel CMOS AF is excellent at automatically recognising a face, focusing and following it while it moves.
Support for in-body Electronic IS
The EOS C300 Mark III incorporates Electronic Image Stabilization (IS) into the camera body, supporting 5-axis camera shake correction. Even when used with lenses with no electronic lens communication, Electronic IS is possible by manually inputting the focal length.
Automatically obtains focal length
When a lens that supports data transmission is attached, focal length data is automatically received through the digital contacts for shooting with optimized Electronic IS.
Electronic IS with non-electrical contact lenses
Shooting with Electronic IS is possible even when a lens that does not support data transmission is attached by simply manually inputting the focal length. It is also compatible with anamorphic lenses.
Focal Length can be saved
Just select focal length during shooting to shoot with an electronic IS effect optimized for the settings.
The EOS C300 Mark III features an advanced 12G-SDI interface which has four times the bandwidth compared to 3G-SDI, simplifying 4K workflows by enabling it to output 4K 50/60p over a single cable. Similarly, the HDMI interface can also deliver 4K 50/60p over a single cable.
Built-in ND filters
Equipped with a robust built-in electronically controlled ND filter system, EOS C300 Mark III supports 2/4/6 and an extended 8/10 stops, making it possible to create an image with a shallow depth of field, even in the daytime.
The On-Screen Display (OSD) shows a range of tools that will not interfere with the information on screen. There are several options to choose from according to your needs.
Anamorphic lens support
EOS C300 Mark III supports anamorphic lenses by electronically de-squeezing the image in the viewfinder and on connected monitors for viewing.
User LUT support
Users can design their own LUTs and load them onto the camera for precise-look monitoring, also, users can apply different LUTs for each output terminal.
The EOS C300 Mark III supports ACES 1.0 of the Academy Colour Encoding System. Using Canon supplied IDTs, images captured on the EOS C300 Mark III can be imported directly into the ACES compatible systems.
Compact, lightweight and reliable
Approx. 1,750g lightweight body enables it to be comfortably rigged with gimbals and hand-held rigs, making it ideal for various shooting conditions.
Pioneering Auto Focus technology
The EOS C300 Mark III features Canon’s Dual Pixel CMOS AF Technology which offers high-speed Continuous AF. Users also benefit from smooth, intuitive touch focus operation with the 4.3-inch LCD monitor LM-V2, as well as an improved focus control that recreates a more natural focus pull.
To further fine tune AF performance, the EOS C300 Mark III offers the ability to set the AF tracking speed and response.
Multiple recording formats support broadcast workflows
Dual card slots enable simultaneous internal recording of 4K Cinema RAW Light files (10/12-bit) or 4K XF-AVC files (4:2:2 10-bit) onto CFexpress cards. XF-AVC supports ALL-I which delivers the best quality, and Long-GOP which enables longer recording times through higher compression. A Proxy can also be recorded onto an SD card, making editing work more efficient.
