DJI Osmo with X5R - 4K Raw video

http://www.eoshd.com/2015/10/why-dji-osmo-is-actually-a-4k-raw-micro-four-thirds-camera/

Any chance to have a housing for it? I am really interested at the 4K raw of X5R.

Gimbal for underwater use doesn't exist, well, at least unheard of for consumer. If you want RAW 4K video, your best option is probably Black Magic products, like the URSA or the URSA mini. They have a 4.6K camera that I remember is priced reasonable for today's standard. Criticism is their battery life isn't great etc.
