The Canon EOS R3 is a 24.1-megapixel full-frame mirrorless camera built around a back-illuminated stacked CMOS sensor, the DIGIC X processor, 30fps continuous shooting, 1,053 autofocus points, 6K video recording, and a weather-sealed magnesium-alloy body rated to 500,000 shutter actuations — all in a camera designed from the ground up for professional action and sports photography. With the Canon RF mount, you get the most out of modern Canon RF lenses.

What makes the Canon EOS R3 special?
The Canon EOS R3 sits in an unusual position in the mirrorless world — it's not the highest-resolution Canon body, but it is a highly capable action camera. Here's how it stacks up against the cameras people most often compare it with.
Canon EOS R3 vs Canon EOS R5 / R5 Mark II: The Canon EOS R5 and Canon EOS R5 Mark II both offer higher megapixel counts, making them the better pick for large-scale print work and studio portraiture. The R3 trades some of that resolution for a much faster readout speed, a stacked sensor architecture that virtually eliminates rolling shutter, and a body built to the same durability standard as a 1-Series camera. If speed matters more than pixel count, the R3 wins.
Canon EOS R3 vs Canon EOS R1: The Canon EOS R1 is Canon's absolute flagship and edges the R3 in dynamic range at its native base ISO. The R1 also adds features aimed squarely at the highest-level professional market. That said, the R3's peak dynamic range at its extended ISO settings is strong, and for photographers who don't need every last feature of the R1, the R3 remains an exceptional and more accessible option.
