I tend to agree. I can repeat the problem by pumping down the pressure, and then reverse by releasing the pressure again.
This makes me think there's no issues with the batteries. I cannot test actual diving for a longer while alas. If i could, i could test diving without any under pressure in the housing to see what difference that would make.
IF the problem is a too soft button that pushes down by pressure, however the effect of the water pushing the buttons should soon overshadow the effect of the vacuum pump and give the same result.
For now, the main culprit must be assumed to be a misalignment or bad button.
I think i have to do what you suggests, okuma, however I don't know how to check the button play when the housing is closed. I would very much appreciate suggestion for this. How about you Nauticam dealers, how do you analyze issues like this?
My wag (wild ass guess) is that under vacuum/depth pressure there is an applied force/torque being applied to your camera body.
After pumping down and at depth can you verify that there is a slight clearance between all invividual controls and the camera body?
Two dives today where I repeated the problem on both dives. This brought some more leads. The issue is this:
The camera shuts down after sometimes one, but most often repeated shots, at second or third shot in a series.
I take the shot, the rear screen momentarily blacks out, as usual, but instead of showing preview of the shot taken (i've set to 2sec) The camera flashes the "IS1" symbol red on the right side. Blacks out again and shuts down.
In order to get started again, I have to cycle the camera on-off again.
This happened frequently on both dives today. The housing was not opened between dives. Most shots taken with manual flash 1/64s (to trigger external strobes with fibre) all in M mode with 8m fisheye at 800Iso and f3.5-6 s at 1/20-1/200.
Fine, water temp from 13-9 degrees centigrade. surface temp about 17 degree centigrade. 2h between dives. Depth 9-30m
At home, I opened the housing and tried the camera with the same set-up. The issue does not repeat with the camera outside of the housing!!!
I initially though that the camera image stabilisation is broken, however it works a charm on land. What can be the issue?
I can only conclude that there must be something wrong with the Nauticam housing?!?
Issue: Does not like vacuum!!!!
Finally I tried to seal the hosing again. No issues. But when activating the vivid housing leak detector, and pumping it to flash green, the problem comes back. And it is repeatable!
So, what on erth is this, is really my camera individual pressure sensitive, or could this be a function of one or several stuck buttons? Any ideas for finding out?
