Great variety of shots, Marco. I just got the 32mm and look forward to taking it out and about, especially after seeing all your shots.

Sprained my left wrist and ankle by stepping off a 1m drop - whilst looking up instead of down on Wednesday morning as I walked down some stairs. So i left my FF DLSR and heavy White lens at home and took the M6 with me to lunch instead. Caught a nice shot of the Pacific Ocean from cliffside (above) before lunch with family. Many years ago, I once found a Giant Pacific Octopus clinging to a rock underwater - almost exactly where the guy in the Kayak is paddling above. Tried to try it off the rock but it's arms were as thick as my thigh and when I felt the strength of it I knew then to leave it well alone. I once had a much smaller one grab my underwater camera (which was attached to my wrist with a strap) in Hawaii where I was snorkeling off Maui in the 1990s... and it let go as I was about to lose consciousness from lack of air. Those things post a considerable risk because of their strength underwater. As a result, I won't ever dive without precautions and a knife. I'd love to take the EOSM underwater but I can't see that happening with the current touchscreen design.
As for using the M6 underwater, I bought this cheap Seafrogs housing for the M6 from eBay for around $300. I haven't taken it to any great depths, but it has worked on a few snorkelling and beach trips.
The M6 has enough dials to make it ably operable underwater. The only thing with this housing is that it annoyingly does not have a knob for the exposure compensation dial. That housing in particular is for the EF-M 18-55mm, but since EF-M lenses have the same barrel width, you can use it with most EF-M lenses. The zoom mechanism works with the EF-M 11-22mm as well.
I was snorkelling in the Royal National Park last week and it was a surprisingly fun experience, as with most things EOS M. I used the 22mm to give myself the extra speed if needed. As you've noted, the water has been pretty murky with all the winds and storms and I'm still getting the hang of using the housing, so the photos below are nothing to write home about, but I attribute to user error more than anything. All in all, I think the M6 with a cheapie housing is a pretty capable underwater camera, particularly given that you can use quite a few lenses with it.
These photos have been adjusted in Lightroom to improve the contrast and colour.

Very murky water, but the M6 is still managing to focus well and get a fair bit of detail.
Getting lots of details on the snail

It's good to be able to take the camera out to the beach without worrying that the next wave will drench it.
