Canon EOS C400: A Powerful New Full-Frame Cinema Camera
Introducing the Canon EOS C400
Canon’s EOS C400 represents a major step forward in the Cinema EOS lineup, combining a 6K full-frame back-illuminated stacked CMOS sensor with a compact, professional cinema-camera design.
Designed for filmmakers, cinematographers, production companies, commercial shooters, documentary filmmakers, and live-production professionals, the C400 offers the flexibility needed for a wide variety of production environments.
The camera features a native RF mount, internal Cinema RAW Light recording, advanced autofocus, mechanical ND filtration, professional connectivity, and multiple sensor modes. C
6K Full-Frame Imaging
At the center of the EOS C400 is Canon’s newly developed 6K full-frame back-illuminated stacked CMOS sensor.
The sensor provides approximately 26.7 megapixels in total and supports Full-Frame, Super 35mm Crop, and Super 16mm Crop modes. This gives filmmakers considerable flexibility when choosing lenses and framing their shots. CCanon USA+1
The camera also offers a Full-Frame 3:2 mode, which can be particularly useful when you want maximum flexibility for reframing and different aspect ratios during post-production. CCanon USA
For productions where image quality and post-production flexibility are important, the C400 provides a very impressive foundation.
12-Bit Cinema RAW Light
For filmmakers who want maximum flexibility in post-production, the C400 can internally record 6K Cinema RAW Light at up to 60 frames per second in 12-bit.
The camera also supports 4K recording at up to 120p and 2K recording at up to 180p, making the C400 capable of producing dramatic slow-motion footage when the project calls for it. C
Canon also provides several Cinema RAW Light recording options, allowing users to balance image quality, file size, storage requirements, and workflow needs.
In addition to RAW, the C400 supports XF-AVC, XF-HEVC S, and XF-AVC S recording formats, giving production teams additional choices depending on their workflow.
Triple-Base ISO
Low-light performance is another area where the EOS C400 stands out.
The camera features three base ISO settings — 800, 3200, and 12,800 when using Canon Log 2, Canon Log 3, or RAW recording.
This gives cinematographers additional flexibility when working across dramatically different lighting conditions, from bright exterior locations to darker interiors and nighttime environments. Canon USA+1
The high 12,800 base ISO is especially interesting for productions where maintaining image quality in challenging lighting conditions is important.
Canon Dual Pixel CMOS AF II
Professional cinema cameras aren’t always associated with autofocus, but today’s productions increasingly benefit from reliable subject tracking.
The EOS C400 features Canon Dual Pixel CMOS AF II, Canon’s next-generation autofocus system for Cinema EOS.
This can be especially useful for documentary work, events, interviews, commercial productions, handheld shooting, and situations where keeping a moving subject in focus is critical. C
Professional ND Filtration
The EOS C400 includes a built-in mechanical ND filter system, with 2, 4, and 6 stops available, and up to 8 and 10 stops when using the appropriate extender.
Built-in ND filtration is an important feature for professional cinematography because it allows the operator to control exposure while maintaining creative control over shutter speed and aperture. C
For exterior work, commercials, narrative productions, and documentary shooting, having professional ND filtration built directly into the camera can make changing lighting conditions much easier to manage.
Built for Professional Production
The C400 isn’t just about resolution.
Canon designed the camera with professional production workflows in mind, including 12G/6G/3G/HD-SDI output, HDMI, Ethernet, Wi-Fi, timecode, genlock, return video, and dual mini-XLR audio inputs. CCanon USA
The camera also supports CFexpress Type B and SD cards, with options for simultaneous recording and proxy workflows depending on the selected recording format. CCanon USA
This makes the C400 suitable for everything from independent filmmaking and commercial production to more complex multi-camera and live-production environments.
Compact Cinema EOS Design
One of the most appealing aspects of the C400 is the amount of technology Canon has packed into a relatively compact body.
The camera body weighs approximately 3.4 pounds (1,550 grams) and measures approximately 5.6 × 5.3 × 5.3 inches without accessories. That compact design makes it easier to configure the camera for different shooting situations, whether you’re working handheld, on a tripod, on a gimbal, or as part of a larger cinema rig.
RF Mount and Lens Flexibility
The EOS C400 uses Canon’s RF mount, providing access to Canon’s RF lens lineup and compatible cinema solutions.
For productions using PL-mount cinema lenses, Canon also offers a PL-RF Mount Adapter, providing additional flexibility for professional lens packages.
This flexibility makes the C400 an attractive option for cinematographers who already have an established lens collection or who want to build a system around different lens types.
