The R3 finally brings back the ‘3’ designation for a Canon camera.

It looks to be positioned between the R5 and a future R1.

The original EOS 3D rumour page dated from 2004 and was one of our oldest and is now effectively archived as of a few days ago.

Some of what were 3D rumours did actually appear in the guise of the 5D. Many suggestions seem to be inspired by the EOS 3 film camera, with its ‘eye control’ AF system. If you’re curious, I collected some EOS3 specs at the end of this page (launched Oct 98)

R3 Latest News

2021 May

3rd A few snippets of R3 info appear in a Russian R3 interview [via CR]

As expected, it’s not the ‘flagship’ mirrorless. Not one for me, since it’s intended for wildlife, sports, racing, and photojournalism.

April

21st Until Canon starts to officially ‘leak’ info, there is mostly speculation. A hint dropped to [CR] suggesting that the sensor AF system would be improved. This could be as simple as alternating left-right and up-down pixel splits or it could be as advanced as having four sub-pixels per pixel.

Expect a few new features… Oh and the R1 won’t be along for quite some time.

14th The R3 gets a formal development announcement and will be available in 2021

So, the ‘3’ line is indeed resurrected, along with eye focus.  There are no real specs, but 30fps does fit with ~45MP and the maximum transfer rate of CFExpress cards

Here’s a rough guide to its comparative size against the 1D X III

13th At last, an update for my 3D page with what seems to be an R3 [Nok] due for a ‘development announcement’.

Are we going to see a return of ‘3’? Is this top end or perhaps the high MP mirrorless (R5s/RS page)

2018 December

20th Mirrorless EOS R is the future, so I’m expecting the next appearance of ‘3’ in a mirrorless model.

This raises the issue of just what the EOS R numbering system will be?

So will it be an EOS 3R or an EOS R3?

And, what many seasoned 3/3D watchers will wonder, is will it have eye controlled AF?

The 3D stuff (dating back to 2004) is now on the Original 3D rumours page
