My associate shoots the HVX 20 under water and loves the results given its limitations, e.g., low light and limited record times. I think that any future investments in professional underwater shooting equipment that is not RED Digital Cinema based is money not wisely spent. I emphasize the professional point here based on the future markets of HD buyers not the new and emerging alternative digital markets. One camera does not do it all.
To date, I have shot RED 4K UW for two major clients with brilliant results. Also shot the first UW RED 4K thanks to Gibby and #8. Now the menu includes a series of tests with the first Aquavideo Pro Housing built around the Arri 8R lens in Jan. This is in preparation for an already contracted major client shoot in RED 4K in March.
Then off to Africa to shoot Mark in 4k shooting his RED camera UW system amongst the sharks - can't wait.
Here is the current RED ONE pro-housing design list for Aquavideo:
1) PL mount lens control - focus and Iris
2) ND - I am researching the ND screw in options.
3) Camera controls - Power and record
4) Monitors - need HD-SDI out to BNC connector on housing. Interchangeable LCD/EVF mounts (uses same cable connector just different attach points on camera)
5) Pole cam attach point
6) Adjustable ballast system on or in the foot per Aquavideo design suggestion
7) We'll name this housing Hollywood - finish is black.
8) Design will utilize the RED brick battery, RED V plate and the RED drive mounted at the rear of the camera tray for easy removal.
9) Pistol grip handles on adjustable cheese plate wings - left hand forward.
10) Vacuum test nipple
That's a pretty damn good start and a sexy ass housing if you ask me. Pictures and performance review to follow soon (Jan 20th?).
