Canon Announces The Development Of Their Newest Mirrorless Camera

After the successful introductions of the Canon EOS R5 and R6, Canon has just announced the development of another full-frame mirrorless camera, the EOS R3. Canon positions the R3 between the EOS R5 and the 1D-X Mark III. The R3 is purpose-built to satisfy the demanding expectations sports photographers have for professional cameras by emphasizing its performance, speed, and reliability. 

There weren’t a lot of details about the EOS R3 in this announcement but let’s look at the details we do know.

Stacked CMOS Full-Frame Sensor

The EOS R3 marks Canon’s first camera with a stacked BSI CMOS sensor. The stacked sensor allows for a fast readout speed which can benefit the camera in every aspect of performance. Faster readout speeds can also minimize rolling shutter. An effect we’ve seen in Sony’s recent cameras like the Alpha 1. 

Electronic Shutter

Canon claims the electronic shutter will take full advantage of EOS R3’s fast sensor. The electronic shutter allows for continuous shooting at 30fps, with full autofocus, and auto exposure shooting modes.

Eye-Controlled AF

One of the most intriguing features announced for the R3 is the eye-controlled autofocus. Canon had this feature in their film cameras released in the 90s. The feature allowed the user to change the focus based on where they are looking in the viewfinder. By putting an infrared transmitter and receiver on the viewfinder, the camera could track the position of the iris. With technology advancing so much since the 2000s, it’ll be interesting to see how effective the eye-controlled autofocus will be in the R3.


Canon’s announcement of the EOS R3 development is reminiscent of Nikon’s announcement of the development of the Z9. Both cameras are bold steps by the manufacturers to compete in the mirrorless market. They both even have a similar body style with a vertical grip built into it. If anything, these 2 camera announcements have shown that the race for the best mirrorless camera not only rages on, it has only just begun.
