We only ever get bits and pieces about the development of the Canon EOS R1, which will be the flagship camera of the RF system. Most of what we're hearing now may have some truth in it, but there are also going to be a lot of unknowns and likely hearsay.
There is a recent report circulating the web that allegedly comes from a Canon Explorer of Light. The unnamed (of course) Explorer of Light claims that Canon's goal is for the Canon EOS R1 is for it to be equipped with an 85mp+ sensor, 24fps mechanical RAW burst and a big bump in sensor dynamic range. All of this sounds terrific, but we don't think these sorts of things would be known right now outside of the labs and meeting rooms at Canon.
A good source also reached out last week and told us that the Canon EOS R1 may not see the light of day until the 2024 Summer games in Paris, France. If that's the case, we expect Canon to start talking about the camera some months before the games begin.
The “halo” or “flagship” product for a line is rarely a big money maker, just based on economies of scale, and we think that Canon is probably more interested in getting new high-volume products to market. The lower end of the full-frame EOS R system will need to be addressed in the next 6-12 months and there are also gaping holes in the RF lens lineup to be addressed.
We also wouldn't be shocked to see a Canon EOS R5 S announced well before the EOS R1.
While us gear nerds love to talk about the best of the best and all that it can do, that really isn't a good representation of the industry as a whole.
