In case you hadn't heard, a little camera company named “Canon” has a new mirrorless camera coming in the near future, it is called the Canon EOS R3. This new camera is in the camera bags of photographers at the Tokyo Olympic Games that opened today with athletes waving to seats.
One photographer that has the Canon EOS R3 in his bag is the highly-regarded Jeff Cable. Jeff has had the pleasure of shooting the Olympics in Beijing, Vancouver, London, Sochi, Rio de Janeiro, PyeongChang, and now Tokyo.

Oh Jeff's blog, he has posted his first shots of the Olympic games at the water polo event with the Canon EOS R3. Jeff is using the Canon EOS R3 and Canon EOS R5 as his main cameras, while the Canon EOS-1D X Mark III runs as his backup or third camera body.
You can check out his gallery of those images here.

My inbox is filling up with lots of “R3 in the wild” content, I will do my best to parse through it all and keep you up to date on any good content about the EOS R3 in the real world.
Keep in mind that the photographers using the Canon EOS R3 are under an NDA (Nondisclosure agreement), and aren't likely allowed to publish full resolution images or give us any more information other than what's already out there.

As much as I agree, I doubt Canon is going to make the top agencies cripple the images they sell if they use the R3. Maybe they'd ask them to remove Metadata, but I'm sure GettyImages isn't being asked to downsize their images to send to Team USA or sell, at the worst you can pretend it was an EOS R5 image that has been cropped down.
i've been following the resolution of files that Getty Images posts on their database since all of their equipment is Canon, including the R3, for their partnership, and there's tons of files over 21 megapixels being posted that can't be taken with a 1dx3, but there's nothing saying these files aren't taken with the R5, so I can't imagine they have to fudge their image quality to satisfy an NDA.
