This is why the Canon R5c can test relative poorly in raw yet approach very close to 13 stops with some noise reduction applied (in camera) and downsampled from 8k, which Gerald showed this in his review.
Of course, dynamic range isn’t the same as highlight roll off, in which the R5c is better than the FX3/A7s3 because it allocates more stops in the highlights. But it comes at a cost of a lack of latitude in the shadows, like the Panasonic s5iix.
The sigma fp and red Komodo are the opposite, so you have to really protect the highlights.
None of this really matters if you understand your camera and exposure strategy.
The Sonys and Canon c70 are balanced in their latitude, which can be better for doc work and run & gun.
