8mm fisheye lens losing view mid dive?

[AlClarence]

Hi, I was wondering if anyone would have any experience with the Olympus Micro 4/3 8mm fisheye lens seemingly losing contact during a dive? I still have light metering and aperture control but a blank screen so no ability to take photos... It's got me stumped as to what's going on

What camera?, I recall having an issue with my EM-5 MkII a while back.  It had a component they replaced to fix it.  I looked it up and it was a frame contact mount unit that was faulty.  It is needed to tell the camera a lens is attached.  

It was back in 2017 so exact details are vague, but it sounds similar to what you report.

It's an Olympus e-m10 Mk4, the thing that is confounding me is that the problem is intermittent and doesn't effect any of my other lenses.  After spending the afternoon troubleshooting as much as I can, I'm thinking sending it in for repairs may be my best course of action

I had the same issue it would do it on or two lenses and the others were fine.  As i recall the repairs weren't too expensive at the time, but turnaround time is currently a while I believe.  In my case it was the camera body which was the problem.  They have a support number you can call and talk to them they can tell you if you need the lens as well as the body or not.

I had around two hundreds dives with Olympus 8mm on EM-1 mkII w/o any issue...
