Sony RX100 iii housing - alternate external strobe/internal flash in Photography Gear and Technique Posted November 30, 2018 I recently bought a Sony RX100 iii for non-dive purposes but had the idea to put it in a housing as my current Canon G10 set up is a bit old these days. Now there are days when I am in full UW photo mode under a jetty and the G10/arm/strobes style set up is what I need, but there are also days when I am out diving with non-photographers covering lots of ground quickly and it would be handy just to have the camera with the internal flash and a diffuser, stick it in program then point and shoot. So the question is, are there housings out there that allow for simple swapping between those two modes? My suspicion is that the aluminium housings like Nauticam block the internal flash with the fibre optic sockets whereas a clear plastic one would allow too much direct light when using strobes. But maybe if there was an aluminium housing with a slot-in/slot-out FOC socket...?
