I have moved from medium format to DSLR with the Sony Alpha 7RII.

I have heard there are modes/features in the camera  that drop it out of 14 bit RAW mode.
Is there a listing of these modes as I shoot only RAW and must stay in 14 bit mode.

Hi,

Fred Miranda has a nice list http://www.fredmiranda.com/forum/topic/1379163

Also, Jim has a nice blog post about the consequences: http://blog.kasson.com/the-last-word/sony-a7ii-12-bit-modes-effect-on-shadows/

As well as the modes identified in the links below I also suspect it drops to 12Bit if using "Crop Mode" when using APS-C lenses or manually selecting crop mode with FE lenses. So best to post crop rather than use crop mode.

No it doesn't, I've since done some checks and switching to crop mode the camera remins at 14bit.

Thanks for the links.

I find this as an undisclosed serious flaw in the camera.
In my landscape work, the camera is proving to be flawed in its color depth as it isn't even a true 14 bit RAW file.

Not happy with it after about 3 months of testing compared to the H5D 50c WiFi I had.
I shoot color, then convert files to B&W.
The conversion of a 16 bit Hassie file verse the file from the 7RII shows a dramatically better gradation of the sky/clouds with the Hassie.

Expect my life with the Sony is going to be short lived.
