#394652 Reflective prism for flash trigger

Posted by JohnnyQuest on 22 April 2018 - 04:21 PM

Nauticam makes an optical trigger that sits on the hotshot and just fires the flash straight ahead. Since it doesn't have little LEDs that connect right to the optical bulkheads, you need to use the prism to redirect that straight ahead light, upward. The prism reflects the light up into the bulkheads. If you use a trigger that has the little LEDS you need to remove the prism and put the LEDs directly into the bulkheads. I have a Nauticam housing, but I'm using the UWTechnics TTL trigger so I removed the prism.


If you download the user's manual here, it will tell you about removing the prism http://uwtechnics.co...housings-detail

I thought this was a very good starting point:

#321481 DS-TTL II with the S&S YS-D1

I am also still struggling with this issue.. by the way I am going to use YS-DS1 with mirrorless LUMIX GX1 with nuticam.

I set it on DS-TTL II and had very good results with my 7D. The "other" slave seems to be for non-compatible cameras. I did have the lock up issue that was supposed to be fixed by the recall. Backscatter gave me two replacements. I'll test them in real water next month.
