Impressive work. They look tiny. What are those riffled structures?

Lots of great information. Thanks so much. I see now that this will take much study and careful observation - a big change from just jumping in and snapping away - but a great deal more interesting. Thanks again, Dave

I'd like to plan a one week trip to the Caribbean in November to look for nudibranchs. Is there one area better than others to increase the chance of sightings, or is it uniformly just a matter of looking carefully? I've checked out the book "Cayman Nudibranchs" by Turner, et al; and at this point, suppose that would be just as good a destination as any other.

Here are the dimensions I used for milling my case. Note the shoulder that makes it a bit more complicated.

I use the Howshot cables for Inon strobes from Diversion. I assume they're multicore, but I haven't verified that. I get the same results with Meikon cables and with unknown brands from China via ebay.

Thanks Chris, Since that posting, I've been using the adapter you show in the right port of my Seafrogs a6500 case because the left side port doesn't get enough light diverted from the onboard flash to trigger a strobe reliably. The commercial two-port plastic bulkhead adapter is all I could get for my a7Rii case. I've also used the double hole bushing to relay trigger light to two strobes from a Nimar led trigger, and in that case neither strobe would trigger. One strobe would trigger, although not reliably, with a single hole bushing, possibly because the fiberoptic cable was better aligned with the axis of the weak led. These problems go away with both single and double hole bushings when used with the flood of light from the a6500 onboard flash.

I modified my a7Rii Meikon case for the dual fiberoptic bulkhead connector that comes with the Seafrogs a6xxx Salted Line case. I'm hoping to interface the UW-Technics converter with it so I can keep the standard synch cable connector as well.

I've been using a YS-03 for several years now, maybe 50 dives, with a Sony RX100iv in a Fantasea case and an a6500 in a SeaFrogs Salted Line case. Works great for macro, no complaints. If I had it to do over, I'd pay the extra $100/ea to get the YS-01 with manual and target light options. But if you add another $200/ea you could get the Z330. I think they call this mission creep. Attached are shots from a trip to Loreto, Mexico last month - 80 ft, dark, murky, and cold. a 6500 with 90 mm macro lens and YS-03.

I received two Z330s today. It took 6 weeks to deliver. And ignoring the warning in the instructions, they work fine in parallel via a Y sync cable,as Pavel and others have said they would.

Thanks, And replied to your PM.

Hello Bevan, Very interesting. I'd like to try it with my a7RII, with the LEDs on two short stalks to mate with a custom fiberoptic interface window. Any way I could get one? Thanks, Dave

Thanks, Doc I wound up at Loreto because it’s a short 1 1/2 hour flight from LA. La Paz has 6 hour layover in Mexico City. Last dive tomorrow. Still a little cold in full 5 mm with 2.5 mm shorty. Lots of cold upwelling. All despite 90 deg air.

Excellent. Thank you

Hello Pavel, Referring to the TTL converter for Sony a7Rii to be released, fitting it to a Meikon case, can you recommend a retrofit to the single hole in the top of the case for fiberoptic cables to two strobes? Or would the case have to be modified for two optical bulkheads? Below are diagrams of the Meikon case hole that fits their standard sync bulkhead. Thanks for any help.
