I have a water damanged Nikon D3, appx 4 years old, apx. 107000 actuations.
The camera got a brief partial dip in a river (lense not affected), and was working immediately after. but after a few minutes, checking for pictures and the house dry, the camera would not switch on.
Visually no water could be seen in any acceissible openings. The battery workes fine in another camera, so it may be many things. It was working flawlessly until this incident.
The camera is sold only as camerahouse with cap to cover the lense mount.
If this is of any interest or more information is needed then let me know.
The camera is located in Floroe, Norway
