Here's one I found at 13 feet in fresh (slightly chlorinated) water: Probably avius potterius

Interesting claim about processing power needed on the 12K camera's page at BlackMagic: Obviously I have not tried it (grin)...

Got one - thanks!

Looking for a Canon G16 housing, preferably Canon brand, for a friend who dives every day and wore out her older housing

One of my favorites is: Life Cycle of Fish  by Ned DeLoach If you're already a member of REEF, just log in and watch. If not, it's easy and free to become a member. Ned gives a very fine overview of the reproductive strategies of many different species.

I use an AX700 so a bit different from the Panasonics. My shutter speed is set to 1/125. I formerly used 1/60 but find that action is a bit crisper at 1/125. The only time I'd be tempted to go back to 1/60 would be an ultra low light situation. Your thoughts? Tom

Neptune63, This is probably your best bet: http://www.southern-nikonos.com/index.html Tom

Thanks to everyone I now have a new set of clamps. No more needed at this time. Tom

Gentlemen, Using Ian Marsh's clue for internet searching (DuckDuckGo is your friend ;-)), I'm presently negotiating for a set. I'll post the outcome I hope at least by next week. Thanks to all, Tom

I'd like to find 2, 4 or 6 of the older "wheel" style 1" ball clamps. Here's a photo of one: Thanks, Tom

Int, I use a Sony AX700 and recently experienced a huge improvement in autofocus success underwater. A diver heard me complaining about focus failure using WIDE, and suggested I try CENTER focus. Oh, what a complete difference it has made! Here's a bit of detail: Including CENTER, there are five focus modes available for the AX700 camera in video mode. The other four are MANUAL, ZONE, FLEXIBLE SPOT and WIDE. ZONE and FLEXIBLE SPOT are available if the screen can be touched or if the joystick can be operated to indicate to the camera where to focus underwater. These aren't available on the Gates housing. So until recently I used WIDE, following the recommendation of the "experts." This resulted, as you mentioned, in lots of focus hunting and failures to focus. Very frustrating. When I switched to CENTER focus, magic seemed to happen! Most of the out of focus moments went away - my footage is in focus probably well over 90% of the time. What a great relief! Hope this helps, Tom

What Quinn said!

Disposable underwater film camera something like this one....
