From earlier in the topic:
I am on the Wetpixel Whsle sharks trip and am using a D810 in Nauticam NA-D800 II housing.
The camera fits (just) although it does contact with the top of the housing when removing it. All left hand controls work bar the flash pop up and the new bracketing button.
The right hand side: Working: Shutter release. AF on. Meter mode selector. Rear command dial. Multi function selector, Info button. Mode selector, EV control.
Not working: Front command dial (see below). Record. Live view, Live view selector. AF/AE lock.
I have modified the housing by reversing the gear that access the main command dial, this is now functioning.
First impressions of the camera are good...
