I suppose a question might be if a very high quality fisheye like the 8-15 used with a teleconverter and "defished" can produce similar IQ in the corners to an equivalent FOV rectilinear?

I dive with someone using one with an XT5 and he has nothing but praise. Compared to the Salted housing I had there is no comparison. I'd be very tempted by one at a future date.

What about lenses that are not well regarded above water such at the Tokina 10-17 which has quite a following for UW use?

No DM arrived. I'm considering a redesign using magnets.

The pressure pot could likely do a dome port but not a housing and port. It's also 80# and now in Victoria. The "cap" would be best designed as a hemisphere, not a flat shape.

I just bought a large 10 bar pressure pot from a guy in Bellingham, then delivered it to a friend in Victoria. Would have fit almost anything. What about designing sealed end caps to allow pressure testing of parts off the camera?

I enjoy some out of the box thinking!

This is very exciting. Thinking about custom stuff like N100 down to N85 without adding extension to allow using ASP-C Sony lenses on FF for when I want a more compact setup. Or Nikonos adapters for cameras other than Sony. Basically the weird stuff few people want.

In my experience shooting stills with the camera forward is very challenging, although a monitor or possibly angled eyepiece would help. The mount I designed has detents at 90 degree increments and has a toolless camera removal which works okay underwater.

There are also the 3d printed fixed focus/aperture lenses using the optical components from disposable cameras.

I have a 3D printable mount that has been tested up to ASPC sized cameras, I'd be willing to share the CAD file so long as you don't commercialize it.

The ones I posted take a Sea&Sea connector, which would make screwing them in a bit easier unless some sort of rotating component was built in. In my case I'd like straight connectors with some flex if that makes sense?

I'll take it!

They thread on like a cap. I can thread a 1/4 compression fitting on there. But I'm guessing something in TPU could thread on without actually having to print threads. NauticamOptical Fiber Connector for Nauticam (to use with 26216)(...For use with the Nauticam Universal Fiber Optic Cable. Provides connection to Nauticam housings with threaded optical cable bulkhead.

That's a deal. I'll measure the length I need, if I can cut it with nothing special I'd probably order twice the length I need to have spare. S&S plug on one end and Nauticam on the other.
