Here's a comparison at ISO 100, exposed to protect highlights, 2560x1072 (14 bit gives 28 seconds, 10 bit is continuous) in greyscale crop mode. I lifted the shadows a bit to see into the blacks. 14 bit is top left, 10 bit is bottom right.

Try 3 pairs of DNGs here:

I think that 10bit will work really well, as long as there's nothing you need to pull out of the noise floor. Remember that the 2K DCI spec for Cinemascope is 2048x858... which is 80% of the above res. This allows for a significant amount of re-composing / stabilising / downscaling for increased resolution.

Interestingly, both types of DNG are the same size in bytes - don't know what's going on there.

This 10 bit footage looks really bad. Do you think it is worth the hassle compared to a 8 bit log?

I am testing this on 5d3 113. I am really shocked, with the old PC mlvfs (with pismo) 10 and 12 bits works like a breeze I am using resolve 12.5, sometimes only the first frames are corrupted but the rest is perfect. 10 and 12 bits recording is really a huge boost in recording times.

The most important and useful modes for me now:

1920x648 (1920x1080 16:9 after desqueeze) 50 fps 12bit - continous - (previously only 2,35:1 was continous)
1920x648 (1920x1080 16:9 after desqueeze) 60 fps 10 bit - 25 sek

1920x1080 37 fps 12 bit - 13 sek
                              10 bit - continous

2560x1320 25 fps (max vertical resolution available) 1.94:1 aspect - 10 bit - continous

2880x1226 2,35:1 25fps 10bit  - over 2 minutes
                              24 fps 10 bit - continous

I checked those recordings in resolve and sometimes there are first and last frames corrupted but no problems during clips.

Can you also do some DR comparison?

I will do this little bit later, i expect there will be less ability to recover shadows/highligts especially in 10 bits - but as a tool - 10bit is gladly welcome. I am very excited because of usable 50/60 fps in 16:9 aspect. There are also 11 and 13 bits settings, i have to also try them.

The 11 & 13 bit settings are not selectable. I'm not sure it is really necessary though

I'm with you on that one. My take home message is: the advantage of 10bit amounts to a 29% increase in resolution or fps or recording time, or some mix of all three.

If you don't need any of the above, stick with 14bit. But if you do, make sure nothing you're interested in lives in the noise floor (which is shown on the RAW histogram as a dithered pattern - stay outta there!).

Exactly, 10 and 12 bits are just a great tools, for me ability to shot 14bits and then drop to 12bit to record 50fps continously with 16:9 aspect is just great. I have also tried 65fps and get 12 seconds of 10bit raw 65fps 16:9 -  it would be just a great addon in situation when 37% slomo is needed ;)

if possible may I ask you to take a picture of this histogram and draw a circle around the area that express the amount of noise please? I wish to understand better please, it looks very very useful! :)
