Oh I have two Nauticam pumps, one with the end completely ruined and the other mot far behind. That print will be brilliant.

It's really the same as a port.

The lens has a rather significant o-ring which seals to the adapter.

I've got a 65 I could sell if you want to DM me.

You may not like the fisheye perspective for wrecks, that is down to taste. A factor to consider is that behind a dome port you'll have to stop down to get decent sharpness in the corners. There is plenty written by far more intelligent people than I am about why.

I can't even hear the buzzer through a hood, so I'm with Dave.

I've had a Sea Frogs, never again. To my mind where FF excels is wide angle, although most can use the 10-17 Tokina which is well liked. MFT is probably the most versatile, has lots of quality housings and anything from the EM1 Mk2 or newer will have outstanding autofocus. The used market is your friend.

Guess I need to get back in tomorrow then!

Those pictures look great Dave, my last dive in Washington I could barely see my fins 😅

I have had nothing but problems with several GoPro standard housings. Having to shim the camera precisely and even then not working correctly.

Comparing the length of lenses and ports to the Nauticam chart for Sony it comes back as 28mm. But that is me working back rather than actual measurement. And of course people have found that some adjustment of camera position is needed to get it focusing correctly.

An aftermarket aluminum housing with better buttons is worth it.

I'm especially interested in the levers and controls plus how it adapts to Nauticam ports.

For macro I only solo dive. I can manage wide angle or CFWA with a team mate but it's definitely more work.
