In Topic: Looking for double flip adapter for wet lenses

19 May 2015 - 07:48 AM

That is why I suggested using a 77-67 mm step down ring  (I have the Nauticam single ones for both the 67 and 77 ports) and the Saga dual flip adapter. You suggest that it might vignette but that seems unlikely since the lens itself is only 67 mm.

In Topic: Fix Neo video lights, any flooding issues? as sealed as a sola?

I am continually surprised by how often something like this happened. We have a L&M underwater housing that uses 4AA batteries to drive the video back. ON a dive, the batteries shorted and melted the plastic battery carrier. We were able to salvage the dive trip with some wires taken from an old lamp at Maluku divers so everything worked at least. We took the carrier to L&M at DEMA and they said they had seen this before. I suggested a $0.05 fuse would have stopped this problem; apparently that was not an option of them. Now we travel with several battery carriers home made from radio shack. 

Electronic failures that lead to shorting are not a sign of reasonable design; no single point failure should do anything other than turn off the light.

In Topic: Nauticam flextray not so good, alternatives?

I am quite sure Nauticam will replace them. Alternatives are available from say ULCS with much beefier handles. I am a bit surprised at yours breaking, can you see definite corrosion at the break?

If you are using a 67 mm lens it should be clear that at 67 mm flip (like the Saga) has to work fine.

The fact that the contact "melted" suggests to me at least that the design is significantly NOT robust.
