D850 sraw, mraw resolution please compare
1

D850 ISO64 sraw

D850 ISO64 mraw

D850 ISO64 14 bit lossless raw

D4 ISO100 14 bit lossless raw

Hopefully someone who better knows what they are doing and has a proper test chart will do this correctly soon. Till then, I printed out a test chart and shot this using tripod, remote, 1s delay, live view focus.

My eyes aren't that great so I was hoping that people could chime in and rank the images in terms of which has most resolution. For the D850, it will of course be:

(most) 14 bit lossless (45MP) >>> medium raw (25MP) >>> small raw (11MP) (least)

What I would like to find out is where the D4 image places in this.

You will need to download each image in DNG format from links above, process and resize to the same size - I used 4128 as that is the native size for D850 small raw files but any should work the same. I would suggest outputting to TIFFs as JPEG compression may affect results.
