What does 16 stop dynamic range ACTUALLY look like on a mirrorless camera RAW file or LOG?

I want to see it.

Real world subjects only (like landscape scenes, people, and so on).

The high dynamic range (using DGO technology) in the Sony A7 V is for low to middle ISO stills when using the mechanical shutter; DGO is not used for video, and certainly there won't be any 16-stop dynamic range at ISO 3200 or 8000. The claimed 16 stops is likely achieved on a signficantly downsampled ISO 100 still image and criteria based on engineering dynamic range  (SNR = 1).

 

Do the EOSHD website and browsers used by visitors support high dynamic range photos on Super Retina XDR and other HDR screens? Otherwise, I'm not sure what the OP is looking to see. Having lower noise can't harm the image and it's up to the user to make use of the higher fidelity, or not make use of it.

For a still image?  Photons to photos has never measured one - their highest measured DR is between 13 and 14 stops on some Phase One.  They have the A7V and the GFX 100 II about equal at ISO 80/100.  If you want some landscape photos from my GFX 100 II, I can certainly share a few.

For video, it's not exactly a mirrorless (but same sensor as in the mirrorless S1R II), but supposedly the Ronin 4D 8K in DR expansion mode has 16.3 total stops on the cined chart, but like most cameras, a lot less than that at a usable SNR.

I want to see one of those 13 or 15 stop dynamic range RAW files everyone is raving about

None of those images show the full dynamic range.

It's a low light test more than dynamic range.
