Interesting to look at the review of R6 - it shows that using electronic shutter (12bit) drops the ability to push shadows by about 1- 2 stops (my assessment) vs mechanical shutter (14 bit) non plus (8fps).
This suggests that R5 pushing at low iso's will be diminished significantly? when using electronic shutter or H plus.
[I suspect that this is also true of Sony and Nikon - DPReview has just not presented this previously ]
So shoot at slow fps (14bit) at 8fps if you can on R5. And don't bother with the A9 - it can't do it (14bit continous)
Bill Claff measured that already for the R5 (https://www.photonstophotos.net/Charts/PDR.htm). Compared to the A9, for example, DR drops significantly in ES for Canon. His A9 results showed hardly any difference.
Thanks - Sony A9 does not drop but it was not as high as Canon was in dynamic range to drop from. I presume because its always on 12 bit whereas Canon is on 14 bit at 8fps and drops to 13 bit at 14fps and 12 bit at 20fps? In other words canon has better dynamic range than a9 if you can keep your fps below 8fps (14 bit) and <=iso800. Otherwise, at 20fps or =iso800 they are even on dynamic range. And at 14fps (13bit) <=iso800, canon is also better than a9.
