In Topic: Olympus 12-40 F/2.8 and the Zen Underwater DP 170 n85 port

10 September 2014 - 12:04 PM

The short answer is yes, the Nauticam port chart recommends the 7" acrylic for the Olympus 12-40mm and the Sony 10-18mm, the other lenses show the 6" Nauticam port but should work well in the 7" port. They also just released a new port adapter and extension for the Nauticam 180mm optical glass port for these lenses. I still would recommend the ZEN DP 170n85II port for anyone wishing to go with optical glass.


Excellant.

DP-170-N85-II is the new version (the one I have) and has an additional 30mm of extension on top of the original. So a total of 60mm of extension, plus the ID of the port body is 77mm allowing the larger diameter lenses such as the Olympus 12-40 or the Sony 10-18 to be used. The DP-170-N85 II is compatible with:
Panasonic 7-14mm f/4
Olympus m.Zuiko 9-18mm f/4-5.6
Panasonic 12-35mm f/2.8
Olympus m.Zuiko 12-40mm f/2.8
Sony 10-18mm f/4 E-mount


Hi Phil,

Thanks for the very informative post reference the zen dome. I have the Nauticam 7" dome which I'm hoping to utilise after a change to the EM-1. From your list on compatible lenses for the ZEN dome above, do you know if those same lenses are suitable to use behind the Nauticam dome as well?

In Topic: Sony E 16mm F2.8, ECF1 Fisheye - reflections from Dome Port

03 September 2014 - 07:04 PM

I have the 10-18mm and used it for the first time a month ago in the Caribbean. Previously I used the 16mm with adaptors wideangle and fisheye. I have to say the 10-18mm is much better than I expected.

It produces sharp images across the frame with fantastic contrast, whereas the 16mm with WA and FE were soft on the edges with noticeable CA.

The 10 -18mm was connected to a NEX-6 behind a nauticam 7" dome. I also didn't notice any reflections whilst using it...

(It will be for sale soon as I'm rethinking my whole photography setup)

With regards your strobe question and distance. The further away you are the less light will reach the subject. Do a google search for inverse square law with strobes, it explains it perfectly.
