The EOS R3 arrived in 2021 as Canon's dedicated sports and photojournalism flagship, built around a 24.1-megapixel stacked full-frame sensor chosen specifically for extreme readout speed and continuous shooting performance rather than maximum resolution — the same reasoning that later shaped the EOS R1's own sensor choice.

The R3 was also the first Canon body to introduce Eye Control AF in its modern mirrorless form, letting the camera shift its active autofocus point based on where the photographer is looking through the viewfinder — a feature Canon originally built for the film-era EOS-3 decades earlier and revived specifically for the R3's sports and photojournalism-focused design before extending it to other bodies in the lineup afterward, including the later R5 Mark II.
Canon also gave the R3 a genuinely novel electronic viewfinder-based eye-tracking calibration process, letting each photographer register their own eye behavior for more accurate focus-point selection than a one-size-fits-all system would achieve.

Frequently Asked Questions
How does the EOS R3's resolution compare to the EOS R1's?
Nearly identical in practice — both use a 24-megapixel-class stacked full-frame sensor prioritizing readout speed over maximum resolution, so their pixel pitch, circle of confusion and depth-of-field figures land within a rounding error of each other, with the real differences showing up in autofocus generation and body design instead.
