Underwater housing for the Blackmagic URSA Mini Pro Cinema Camera

order code: A-BM2

Choose the affordable URSA Mini 4K and URSA Mini 4.6K models with cinema quality, fixed EF or PL lens mounts, and dual C-Fast card recorders. Or choose the new, advanced URSA Mini Pro 4.6K with powerful broadcast features and controls. The ewa-marine A-BM2 housing was specifically designed for all of these Blackmagic URSA Mini Pro Cinema Cameras. The housing is rated up to 10 meter depth / 33feet.

Designed specifically for these cameras the housing A-BM2 is manufactured from double laminated PVC film and has an integrated, optically neutral flat glass port and comes with special ewa-marine CA adapters for connect the lens to this port via the lense's filter thread.

The cameras side-monitor can be used inside the housing. Once the camera is installed into the housing, just release press studs of  the side flap that is integrated into the housing. And if you do not want to use it, just fold in that flap again. Some users might prefer to use a top mounted monitor as well. We have added a pouch that will accept the top mounted, standard Blackmagic Video Assist 5” all-in-one monitor or the Blackmagic Video Assist 4K 7” high resolution monitor. You might find these ideal if the lens is dipped into the water for that underwater shot while you are still able to look into the monitor above water.

Perfect for snorkeling or shallow diving, sandy, dusty, humid or foul weather conditions this housing will give your camera the best possible protection whilst being fully operable.

It has a pair of non-corrosive and seawater resistant clamping rails which fit together for perfect sealing. They tighten by means of knurled thumb screw knobs.

It is supplied in a black carry-case.

The A-BM2 housing is currently limited to the following lens specifications:

- For lenses with a maximum length of 150mm / 6 inches

- For lenses with a maximum diameter of 100mm / 3.94 nches

- For lenses with a maximum filter diameter of 82mm

If you want to use lenses with a larger filter diameter than 82mm, ie. 95mm, please note our information for custom housings:

If you intend to use your Blackmagic Ursa mini with lenses that do not fit the above specifications above, we can supply a custom housing with a larger front port (128mm Ø). Please let us know which lens you intend to use, ideally with a link to the technical specs of the lens. We can manufacture a housing and supply it to you at short notice.

Designed specifically for the Blackmagic URSA Mini Pro (both the original version as well as the Mark II launched 2017) the housing A-BM2 is manufactured from double laminated PVC film and has an integrated, optically neutral flat glass port. With this housing you will receive a set of adapters that fit the filter threads of the most popular lenses on the market today. By means of this adapter the camera is then docked into the housings front port, ensuring that the lens remains parallel and centered behind the front of the lens. Just as if it were a clear, neutral optical filter.

It has a pair of non-corrosive and seawater resistant clamping rails which fit together for perfect sealing.They tighten by means of four screw knobs. There is also the practical, adjustable carry strap on the clamping rail.
