Thanks @Chris Ross @Architeuthis That all looks like good advice, I'll mock it up when the new kit arrives and see what depth of adapter is needed, the 8mm Zuiko does look to be quite a physically long lens compared to other fisheye options (including the Panasonic Lumix 8mm), so it may be that one of the stock N85 to N120 adapters will work.

Thanks @humu9679 , Never got to dive Hawaii but it has been on my bucket list from a young age. Passed through a few years ago on my way to Truk, swam on Waikiki and paid my respects at the USS Arizona but didn’t get to dive. Hopefully next time.

Thanks Maria, Yes, the vis can be epic alright. In late August / early September I have had 30+ metres visibility (cover boat visible from the bottom) on sites like Ling Rocks off Kinsale or Dolus Head just north of Valentia, and off the northwest coast (Donegal) the vis can be even better - think of Leigh Bishop's natural light images of wrecks like the SS Justicia and HMS Audacious. As for pics, I'll post some when the results aren't completely embarrassing. 🙂

Hi All, Looking for some advice on modifying a Zen dome. I have a 100mm (4") Zen DP-100-N120N dome which I use for CFWA with a Nikon 10.5mm fisheye. I'm planning to move to Micro 4/3 (OM1 Mk. II in Nautcam) and would like to bring the dome with me. Nauticam make a couple of N85 to N120 adaptors but they all seem to be too deep to use with the Olympus 8mm lens I am planning. The base of the dome seems to be held in place with a series of allen head bolts so presumably it just unscrews. Does anyone know if you can buy a replacement base doe the dome to convert it to a DP-100-N85 that I can use with the Nautical extension ring or is there another port adaptor out there that would work? Appreciate the advice.

Thanks Tim.

I can highly recommend Prescription Dive Masks in San Diego USA. I have a prescription just over +5 on one side with some spherical and +2 on the other. They made me a single vision for the +5 side and a bi-focal on the other for gauge reading to go in my Cressi Big Eyes Evo. Honestly it's like being 20 again. Not cheap but worth it. The only drawback is I spent some time getting lost on dive sites which I know well, it turns out that they don't actually look like what I thought they did when everything was fuzzy. There is a company in Australia that offer the same product line and another called Dive Sight in Sheffield but neither of them replied to my enquiry. There's also a couple of companies that I subsequently found in Poland and Slovakia.

Try sitting the flip holder in hot water. Keep as much of the lens clear of the water as possible. You are trying to heat the holder so it expands to make it easier to remove. If you heat the lens also it will expand just the same as the holder and you will be in the same position as before.

Hi All, New to this site, diving 40 years, underwater photography started as a small child snorkelling over 50 years ago (anyone remember the Agfa Guppy system using 110 cartridge film?) but my habit didn't get out of hand until about 25 years ago. Shot stills exclusively until discovering GoPro 8 or 9 years ago, capability of equipment far exceeds talent and ambition! Still diving a Drager rebreather (hence the handle), a really great rig for photography. D.
