Canon EOS R3 Review: Eye Control Autofocus and a Stacked Sensor Built for Sports Pros

Before the R1, there was the R3. Canon announced it in September 2021 at $5,999 for the body, and for nearly three years it was Canon’s fastest mirrorless camera and the one pros carried to stadiums. It has a 24.1MP stacked back-side illuminated sensor, a built-in vertical grip, and a feature that still feels like science fiction: autofocus that follows your eye.

Now that the R1 sits above it, the R3 has become an interesting buy. It does most of what sports pros need, and prices have come down.

Looking to focus

Eye Control AF tracks where your eye looks in the viewfinder and moves the focus point there. When it’s calibrated well, switching focus between two players or from one bird to another is a glance. It doesn’t suit everyone, especially some glasses wearers, but those who get along with it rarely want to go back.

Behind it is Dual Pixel AF with tracking for people, animals and vehicles, including motorsport. It’s quick and sticky.

30 fps with the electronic shutter, 12 fps mechanical. The stacked sensor reads fast enough that rolling shutter is rarely a problem. Stabilization is rated up to 8 stops with compatible lenses.

Pro handling

The integrated vertical grip holds Canon’s big LP-E19 battery, rated by CIPA at around 760 shots on the rear screen. In testing it recorded more than two hours of 4K on one charge. The body is weather sealed. There’s one CFexpress Type B slot and one SD UHS-II slot, a 5.76-million-dot viewfinder that refreshes at 120 fps, and a fully articulating screen.

Pros also get built-in GPS, Ethernet and Canon’s Smart Controller, a touch-sensitive AF-ON button you swipe to move focus.

Video is capable: internal 6K raw at up to 60p, 4K at up to 120p and 10-bit Canon Log 3.

What to weigh

24MP is low for a pro body if you crop hard. Canon’s R5 Mark II offers 45MP and similar speed for less.

It weighs just over a kilogram. That’s normal with a built-in grip but heavy for travel.

The R1 is now Canon’s flagship, with smarter autofocus, a better viewfinder and more processing. The R3 is the older design.

Who should buy it

Sports, wildlife and news photographers who want a pro Canon body for less than R1 money. Canon shooters who love the idea of Eye Control. Anyone who wants a built-in grip and a long-lasting battery.

If you need resolution, choose the R5 Mark II. If you need the very latest, choose the R1. For a fast, rugged pro body at a better price, the R3 still delivers.
