I was peeved when I couldn't find the bit depth information in the advanced user guide as well. @Neuro found it in the online specs website. Canon certainly left it under the *asterisk copouts :-(I had missed the H+ is 13 bits part :< I wonder how the read out speeds change with bit depth (double for each bit?). In any case, the read out speed of the electronic shutter is too slow for tennis, so I dont get to use 20fps mode.
I did some rough calculations and I think that the issue is the internal bus bandwidth... R3 can handle 30fps/14 bit/24mp which is about the same as 20fps/12 bit/45mp.The R5 @ 14 bit would be about 15% higher bandwidth.
Similarly, 30fps 8k raw (33mp) @10 bit video is also about the same bandwidth. 12 bit would have pushed it over the limit which appears to be ~11Gbps.
I can't see a logical reason why Canon would arbitrarily drop the bit depth for the R5 in ES mode otherwise.
Hopefully the Digic X version in the R5ii will have a different generation internal bus in it.
