My current ancient setup of a Canon 70D in a Nauticam housing/DS161 strobes and Tokina 10-17 with mini dome is basically EOL.

The Tokina is sticking on aperture blades a lot and seems to be discontinued with no way of obtaining a new one.

Going on that im looking at upgrade options.

I have a Canon R6 (mk1) for land use so the obvious route is to house that. Nauticam housings for the R6mk2 according to their site can also take the Mk1 with a kit they sell. Has anyone tried/done this or knows much about it?

That would seem sensible to me as i could use my Mk1 and a potential future Mk2 so extend the lifespan rather than have a disontinued housing for a discontinued body.

Further to that, lens options. Primarily i do wide angle. The crop 10-17 isnt an option so looking for equivalents.

What WA lenses are people currently using commonly underwater? Full frame fisheye, rectilinears and so on? Id want roughly the same field of view as i got previously. Im not a fan of full frame fisheye with large circles that need cropping though.

Canon 16-35 or similar or is that too narrow given its not fisheye? Sigma 15mm f/2.8 ? Canon EF 8–15 mm ?

Im happy to adapt EF lenses and not need just RF.

I already have a RF-16 f2.8 FWIW.


Its been so long since i looked at options can anyone suggest common lens WA setups and ports to go with the nauticam (or other options, WACP or whatever) ?

Strobes i guess ill have to keep for cost reasons but im currently utterly unable to find a new battery for my DS161 which is another issue.

Ideally i want to stick with Nauticam although i know i cant actually use the port or anything from the old setup sadly. Id look at buying likely here in Japan as with tax free etc its over £1,000 cheaper than the UK cost. Or happy to consider second hand - they never seem to come up though.

Also went FF from cropped recently (Nikon Dxxx:s of various generations in Hugyfot housings). Tokina 10-17, Nikon 10.5 and a Sigma 10-20 rectilinear was my work horses. Nauticams wet optics is what pulled me to them when I made the transition. They have rectilinear wide ones and a Fisheye one too. Some will cost you as a whole rig tho, which might or might not be an issue… I shoot Nikon FF so have limited info to share on specific Canon combos for wet lenses. If there’s a good 28-70 zoom it should be good with the WWL1B (guessing here based on Nikon and Sony solutions) and give 70-130 rectlinear degrees throughout the zoom. And then for 24-50 the WWWL1C giving the same FoV in a slightly smaller and very trave- friendly package. I hear the Canon 24-50 is sheit though. Can not say. Nikons z-version is very sharp (but a little plastic).
