I have a Nikon D70 in an Ikelite housing and both are a little over 4 years old. This year, when going to depths below about 100 feet, the display on the camera quits working. The camera still takes the pictures, I just have to bracket all my shots because I can't take a quick look to see if I have my exposure correct.
Obviously the pressure is working on something to stop the display from working. I can't figure out what it is though. As near as I can tell looking through my mask into the housing at depth, none of the buttons on the housing are touching the camera. I have taken the camera out several times, repositined every thing, and it is still doing it.
Anybody else with this setup ever have this problem, and if so did you solve it?
I use a D70s in a ikelite housing and had the same problem.
In my case one of the buttons was 'sticky' and, though it was very hard to see, it was touching the camera.
After taking the button apart and cleaning it, the problem was solved...
Hope this helps,
