Olympus 8 mm fisheye port options

[Bogdan]

Hi everyone,
I shoot a Olympus E-M1 Mark II in a Nauticam housing and usually use the Olympus 7-14 mm lens and 60 mm macro in Nauticam ports. But I want to use my Olympus 8 mm fisheye more and have an old Zen DP-170 port that I was planning on using with it. My questions are:

1. Would I need an extension ring along with the Zen DP-170 port when using the Olympus 8 mm PRO lens?

2. Is there a better choice of ports for CFWA (close focus wide angle) type of shooting?

3. In terms of image quality with this lens, is there a clear winner in the wide angle ports?

Thanks so much!
Bogdan

I'm not sure what version of the DP-170 you have? But the N85 version should fit ok without an extension and give good results. The N120 won't work at all.

Here's the Zen port chart:

If you have to buy a new port, I'd suggest the Nauticam N85 140mm glass dome for best results, although the small 4.33" acrylic dome works as well, but doesn't have as good corners. They require an extension.

Thanks Jack, I'll look at those options.

Is it possible to compare the Zen DP-100 compare to the domes mentioned above (DP-170, Nauticam 140 and Nauticam 4,33")?

Image quality identical to 4,33", or better because of high quality glass??
