After being rolled out to pros at this summer’s Tokyo Olympics, the EOS R3 is now available to professionals at large – and Canon’s latest mirrorless camera threatens to become the most capable all-round tool around for working photographers.

While it’s not technically a replacement for, or even an equivalent to, the EOS-1D X Mark III (as this is ‘only’ a 3-series camera rather than a flagship 1-series), it nonetheless technologically leapfrogs the 1D X III in virtually every department – and stakes a bold claim as the best professional camera, thanks to its 6K raw video, blistering (and blackoutfree) 30fps shooting, and a peerless AF system that enables you to move focus points by moving your eyeball.

There’s no doubt that this is Canon’s fastest and most advanced camera ever, even outdoing the mighty EOS R5 when it comes to technology – not to mention the R5’s record times and overheating when it comes to video. But with the 50.1MP stills / 8K video Sony Alpha 1 already here (and the Nikon Z 9 on the way, with 8K video and a minimum 39MP resolution), does the EOS R3’s 24.1MP sensor provide sufficient pixel density for pro-level shooting in 2021? Has Canon dropped a clunker or been incredibly clever by opting for a 24.1MP sensor and 6K instead of 8K? Let’s find out.

Key features

The EOS R3’s headline features are jaw-droppers. Its stacked, back-side illuminated 24.1MP sensor boasts super-fast readout speeds that can capture photographs at up to 30 frames per second when you shoot with the electronic shutter (buffering 540 JPEGs or 150 raws), or 12fps with the mechanical shutter (for over 1,000 JPEGs or 1,000 raws). The speed of the sensor also virtually eliminates the rolling shutter effect.

Canon Selphy Square QX10: Prints Vivid Smartphone Pics

The Canon Selphy Square QX10 is a departure from the company’s CP1300 Wireless Compact Photo Printer and earlier Selphy models. This photo printer is smaller and lighter than those other Canons, and it’s closer in functionality to the Editors’ Choice HP Sprocket Select or Canon’s own IVY Mini Photo Printer, though it’s still too big to be pocketable.
