What potential drawbacks in it's features do you see for UW use?
Not thrilled with the record time:
Recording and Playback Times : When using supplied 4GBB4 Memory Stick PRO Duoâ„¢ Media Mark2:
High Definition: FH = up to 25 min., HQ = up to 30 min. SP = up to 65 min., LP = up to 85 min.
Priced Memory Stick PRO Duo Media? Google shows it around $55 +/-.
Unless you're going to remove the camera from the housing, remove the Memory Stick, and download it to a laptop between dives, you'll need more than one on a multi-dive shoot.
I'm also not clear on what this means: Memory Stick PRO Duoâ„¢ Media Compatibility : Tested to support up to 16GB media capacity; does not support high speed transfer function; does not support Access Control security function. in case you wanted to buy larger media cards.
Based upon past experience which housing manufactures will be likely to offer a housing for it?
It's the standard HDR-XXX form factor so I would assume any that currently work with the other HDR cameras. Any electronic housing mfr. that currently supports the A/V/Remote jack. Like the L&M Stingray HD, likely also the Bluefin. Amphibico's EVO Elite?, TopDawg etc. Mechanical housings are likely Gates, Equinox and Ikelite. Assuming they sell enough of them to justify any needed control positioning modifications for Gates to justify it if necessary. It's a lot harder to re-tool a metal housing than a poly housing.
Probably just about anybody who makes a housing for the HDR series camera format.
