Innovation, versatility and imaging excellence all merge in the Canon EOS C400 6K Full-Frame RF-Mount Digital Cinema Camera tailored for boundless creativity. The compact camera body is well-appointed and includes Canon's newly-developed 6K full-frame Back-Illuminated Stacked CMOS sensor. The camera meets Netflix capture requirements and has been approved for use on Netflix productions. It features 3.5-inch LCD monitor.
6K Full-Frame Back-Illuminated Stacked CMOS Sensor
The EOS C400 is the first Cinema EOS camera to feature the newly-developed, 6K back-illuminated stacked full-frame CMOS sensor, which offers exceptionally low noise. The sensor delivers faster read-out speeds than previous EOS sensors and when compared to a front-illuminated CMOS sensor, the sensor’s architecture provides improved sensitivity as it increases light capturing efficiency and improves 4K image quality with 6K oversampling.
Super 35mm and Super 16 Crop Modes
The EOS C400 camera’s Full-Frame sensor is capable of capturing footage in both 17:9 and 16:9 formats, and supports the use of Super 35mm and Super 16mm lenses with the appropriate sensor crop modes.
Anamorphic De-Squeeze
A firmware update adds a 1.5x anamorphic de-squeeze display assist option, which will make it easier to see how your image will translate when shooting with anamorphic lenses.
Triple-Base ISO (800, 3200, and 12,800)
The newly-developed, full-frame 6K back-illuminated stacked sensor offers triple-base ISO, which allows the EOS C400 to deliver stunning imagery in a wide range of lighting conditions. With base ISOs of 800, 3200, and 12,800, you will be able to maximize the full dynamic range of the sensor in brilliantly lit or low-light shooting conditions.
CFexpress Type B and SD Cards Slots
CFexpress and SD card slots on the EOS C400 allow for simultaneous recording even when shooting RAW. All recording options are recorded to the camera’s CFexpress slot with sub-recording and proxy options available on the SD card slot.
Built-In Mechanical ND Filters
The C400’s compact mechanical ND filter assembly is specifically designed for the RF mount's short flange back. Buttons for direct control of ND filters are located on the right-hand side of the camera. The C400 provides up to ten stops of ND filtration, allowing users to shoot in various lighting conditions. The use of ND filters allows a camera operator to adjust exposure while maintaining the depth of field.
Improved Autofocus with Dual Pixel CMOS AF II4
The C400 supports the next generation of Canon’s acclaimed Dual Pixel CMOS Autofocus, Dual Pixel CMOS AF II. The back-illuminated stacked sensor provides better light-capturing efficiency, widening the area of the sensor that can be used for AF.
EOS Intelligent Tracking and Recognition
With outstanding speed, precision, and wide AF range, Dual Pixel CMOS AF II uses the EOS Intelligent Tracking and Recognition (iTR AF X) algorithm, developed with deep learning technology, to enable high-performance subject detection.
Mount Adapter PL-RF with Cooke/i Technology Compatibility
The Mount Adapter PL-RF, new to the RF ecosystem, unlocks a broad assortment of PL mount lenses for the EOS C400. The adapter is compatible with Cooke / i Technology’s metadata protocol and includes lock plates for a secure lens mount. Compatibility with the new RF70-200mm F2.8 L IS USM Z zoom lens and the RF24mm F1.4 L VCM and RF50mm F1.4 L VCM hybrid lenses is also added in the firmware update.
Compact, Lightweight, Ergonomic Body Design
The RF mount’s short flange back allows the EOS C400 body to be small and lightweight making the camera just as comfortable on a drone or a gimbal as it is on your shoulder, a tripod, or any configuration where compact size and light weight are important.
