Here are two more. It was really tough in the terrible viz.


In Topic: Canon 8-15mm F4 1.4 teleconverter with minidome

I shot these with the Canon 8-15 and Kenko 1.4 TC behind a 140mm Nauticam mini dome. Frankly, it's really hard to tell the difference in quality between that set up and just the 8-15 alone (I know that's hard to believe). I shot all these in the Marquesas where the viz was between 10' and 25' so these are quite a bit softer than they would be in good viz. I used two S&S YS-D1 strobes and a 5Dmv body.

I have this:

Designed by Pavel who is very active here (and is a great source of information). It works great with my 5D mk4 and my S&S YS-D1 strobes. I believe that Turtle also has a unit available now too, but you don't get Pavel's invaluable help with the Turtle.

In Topic: Reflective prism for flash trigger

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
