Innovation, versatility and imaging excellence all merge in the new EOS C400, the full-frame, RF-mount 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, which supports a variety of sensor modes, including Full Frame 3:2, Super 35mm, and Super 16mm. The EOS C400 features 6K/60p Cinema RAW Light and 4K/120p internal recording along with Canon’s next-generation Dual Pixel CMOS AF II, among other outstanding features. Additionally, the EOS C400 has a variety of interfaces, including return input, Ethernet, and Wi-Fi, enabling control from various Canon and third-party devices.

The EOS C400 is the ideal fusion of both functionality and form, and seamlessly integrates into almost any production with its robust and compact design.

Features

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 oversampling².

Full Frame 3:2 “Open Gate” Sensor Mode

By selecting Full Frame 3:2 from the Sensor Mode section of the main menu, you can shoot using the full area of the sensor and then use that information in post to crop and re-frame your footage to the aspect ratio of your choice. This is especially valuable when shooting with full-frame anamorphic lenses.

Anamorphic De-Squeeze

Anamorphic lenses have an elongated rear element that makes it possible to utilize flare and bokeh effects that cannot be achieved with ordinary lenses. The EOS C400 provides desqueeze magnification options, including OFF/2x/1.8x/1.5x/1.3x.

Triple-Base ISO (800, 3200, and 12,800)

Our 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.

Camera-to-Cloud Collaboration

The camera has native compatibility with Frame.io’s Camera-to-Cloud (C2C) technology. This feature enables you to send proxy files immediately after recording internally, directly from the camera, for a faster and more secure path from production to post. The efficient proxy files don’t require additional processing or conversion, and are available to view, share, and edit remotely between teams in different locations.

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.  Additionally, you can utilize AF while recording in slow or fast motion at speeds up to 4K 120P.

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. In addition to human eyes, face, and head, the camera can now detect the body of a person and follow them with high accuracy.​

Mount Adapter PL-RF with Cooke / i Technology Compatibility

The Mount Adapter PL-RF unlocks a broad assortment of PL mount lenses for the EOS C400 cameras. The adapter is compatible with Cooke/i Technology’s metadata protocol which enables real-time output of lens metadata (focus/zoom/iris position, and other data in addition to lens model information). Additionally, the robust adapter features locking plates that attach to the camera with four screws for a secure and stable lens mount.

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.

Enhanced Level 2 Display

The Peripheral Border Display, also known as Display Level 2, will be enhanced  to show Sensor Mode and Resolution, Recording Codec selected for each card slot, Custom Picture Gamma and color space, Digital Image Stabilization status, and the tilt and roll degrees of the electronic level.

Assignable Buttons

The December 2024 firmware update adds an enhancement to our 60 to 24p pulldown feature, designed with Houses of Worship in mind, that maintains exposure when changing frame rates with an assignable button. The EOS C400 update will also include camera/media switching via an assignable button.

Auto Clear Scan Mode

The Auto Clear Scan setting available in the camera is an automatic shutter mode setting that can detect the frequency of light sources between 50.0 Hz to 2011.2 Hz to help reduce or virtually eliminate the flickering in some LED walls.

Additional Features in June 2026 Firmware Update

The June 2026 firmware update introduces new USB control protocols that allow for gimbal operation of REC start/stop, Iris, Shutter, ISO, and Focus functions.

Furthermore, the inclusion of view assist during playback ensures accurate color and exposure evaluation and SRT auto-reconnect improves livestreaming stability should the connection be lost.

Canon Multi-Camera Control App

The EOS C400 is compatible with the Canon Multi-Camera Control App for iPhone or iPad.

This app empowers camera operators to have control over recording start and stop, focus, zoom and iris, ND Filters, ISO, Shutter, White Balance, Custom Picture and more, all while viewing the image from the camera.
