Sitting atop Canon’s EOS R full-frame mirrorless camera lineup, the EOS R3 is positioned between the EOS R5 and Canon’s flagship EOS-1D X DSLRs. Canon built the EOS R3 to emphasize speed and AF performance especially suited for fast action photography like sports and wildlife.

The 24.1-megapixel sensor is a back-illuminated stacked CMOS designed and manufactured by Canon. The camera can capture up to 30 fps blackout-free with its electronic shutter, and up to 12 fps with its mechanical shutter. Canon states that it has minimized rolling shutter effect when shooting with the electronic shutter.

The EOS R3 has a 3.2-inch Vari-angle LCD and a 5.76-million-dot, 120 fps electronic viewfinder. The layout of controls will be familiar to Canon shooters.

The AF system used in the EOS R3, like the EOS R5 and R6, is Canon’s Dual Pixel AF II, and features “evolved” subject tracking for eye, face and head detection, as well as some animals, cars and motorcycles, in low-light conditions down to EV -7.5. The R3’s system uses “Deep-Learning technology” that improves subject detection and tracking.

The EOS R3 also introduces the ability to set initial focus simply by looking at the subject in the camera’s high-resolution EVF. Users can calibrate this “Eye input” AF for different circumstances, such as wearing eyeglasses or contacts, and also for multiple users of the camera.

Along with the advanced AF system, the EOS R3 also incorporates in-body image stabilization that can provide up to 8 stops of correction depending on the lens used.

Build quality is what you would expect from a pro-grade Canon camera, with weather and dust resistance that Canon states is equivalent to EOS-1D series DSLRs. The EOS R3 features a one-piece magnesium alloy design with an integrated vertical grip.

Card slots of the Canon EOS R3

The EOS R3 has two card slots—one CF express and one UHS-II SD.

For those interested in video, the EOS R3 can capture 6K 60p RAW as well as 4K 120p 10-bit uncropped video with Canon Log 3 support. The in-body image stabilization system is available when shooting video and works with lenses that don’t have built-in IS themselves.

The EOS Revolution Continues: Canon Officially Announces the Company’s Most Technologically Advanced Full-Frame Mirrorless Camera, the Professional-Grade EOS R3

MELVILLE, NY, September 14, 2021 – Building on the success of the EOS R camera series, Canon U.S.A. Inc., a leader in digital imaging solutions, today announced the next leap forward in full-frame mirrorless cameras – the professional-grade Canon EOS R3. The new camera leverages the advancements in technology that Canon has developed since the original EOS R launch in 2018 and bridges the gap between the immensely popular EOS R5 and the world-renowned Canon flagship EOS-1D X line. The EOS R3 is the first “3” series camera from Canon since the widely used EOS-3 film camera launched in 1998.

The EOS R3 camera’s features greatly emphasize superb AF performance and speed with fast-moving subjects. It was designed to meet the reliability and durability demands of professionals, even when working in some extremely challenging conditions.

“The launch of the EOS R3 sets a new benchmark for the Canon EOS R camera system. Canon listened carefully to the voices of professionals when developing a camera to meet their standards,” said Tatsuro “Tony” Kano, executive vice president and general manager of Canon U.S.A.’s Imaging Technologies & Communications Group. “The EOS R3 is a monumental evolution in digital imaging technology. I look forward to seeing the camera in action on the sidelines of sporting events and in the hands of nature and wildlife photographers across the globe.”

The core of the EOS R3 features a Canon designed and manufactured 24.1-megapixel back-illuminated stacked CMOS sensor. The sensor is the first of its kind from Canon, and when combined with the DIGIC X processor, delivers a high-speed readout allowing for continuous blackout-free shooting1 at up to 30 fps in electronic (silent) shutter mode and up to 12 fps in mechanical shutter, with minimum rolling electronic shutter distortion. The combination also increases the high sensitivity, light-capturing efficiency of a native ISO range of 100-102400, expandable up to 204,800 for still images. Like the EOS R5 and R6, the camera features the improved Dual Pixel CMOS AF II with 1,053 AF Points and evolved EOS iTR tracking down to EV -7.5 for subjects such as eye, face, head, animals2, and select cars and motorcycles. In addition, the camera features up to 8 stops3 of in-body image stabilized (IBIS) shake correction.

Leveraging technology and performance feedback from the popular EOS R5 and EOS R6 cameras, the EOS R3 uses Deep-Learning technology to further enhance eye and body detection for even better performance during portrait and action-type shooting. Featuring a new 5.76-million-dot and 120fps blackout-free1 Electronic Viewfinder, the EOS R3 camera will provide photographers with the ability to select the initial area for AF tracking by simply looking directly at the viewfinder location where they want to begin AF. With Eye input AF2 and Servo AF activated, the camera will focus on and track moving subjects at that location in the frame. When Face Detect + Tracking is active, the camera will continue to follow moving subjects around the entire active AF area.

The EOS R3 camera doesn’t just capture spectacular still images, it also packs impressive video specs as well. The camera is capable of shooting 6K 60p RAW and 4K 120p 10-bit uncropped video with Canon Log 3 support, in addition to the possibility for oversampled 4K and RAW movie internal recording. Canon Log 3, which is frequently used in cinema production, helps to reduce the possibility of highlight blowouts. What’s more, the features such as industry standard BT.709, BT.2020 color gamuts, and cinema gamut help to maintain color and tonal consistency. Coordinated 5-axis IBIS helps to correct operator motion or shaking providing dependent video capturing even when using a lens without built-in Optical IS.

Additional features of the EOS R3 Full-Frame Mirrorless Camera include:

  • Canon’s next-generation Multi-Function Shoe that is compatible with a variety of accessories including the Speedlite EL-1, and new accessories such as the ST-E10 Speedlite Transmitter, External Mic and Smartphone Link Adapter
  • One-piece magnesium alloy design, integrating the body with a vertical grip section
  • Weather and dust resistance equivalent to EOS-1D camera models.
  • Mobile File Transmitter application for iOS® and Android® devices allows photographers to transfer their images quickly and easily without the need for wired LAN equipment
  • Built-in Wired LAN, 5GHz Wi-Fi®, USB and Bluetooth® technology
  • Dual-card slots, supporting one CF express and one UHS-II SD

The Canon EOS R3 Full-Frame Mirrorless Camera is scheduled to be available in November 2021 for a suggested retail price of $5999.99*. For more information, please visit
