The Canon EOS R5 Mark II will continue with CFexpress Type B/SD UHS-II card slots

The manual has details for raw and craw in the specifications section, under ‘Still photo file size / Number of shots available / Maximum burst for continuous shooting‘
See: https://cam.start.canon/en/C017/manual/html/UG-10_Reference_0110.html

Note that number of shots is different for mechanical and electronic shutter.

Thank you for that, those numbers are somewhat disappointing.

I'd like to apologise to the EOS-1D X Mark III for my oversight.

Also the 1D X. But most of the other 1-series that had more than a single card had mixed card formats.

I have low expectations for the buffer clearing behaviour in the R5II. I would be happy to be proven wrong, though!

Yeah, Jan Werner is already saying the buffer is better than the R5 but with 30 FPS it clears at the same rate and freezes just the same That's crap Canon, sorry.
I'm personally trading one of my R3s for an R1 and will shoot R1 (main) and R3 (secondary) for sports.
