ewa-marine U-A100 flexible housing

The ewa-marine U-A100 underwater housing can be used on small boats, in the surf, while swimming, snorkeling or diving. It`s easy to operate the camera as its various components and buttons can be operated through the PVC.

The most common, current application is in video production. And to then use this housing with a Sony A7, an adapter like the Metabones and one of the large diameter Canon lenses.

The U-A100 is designed to fit almost all common SLR cameras on the market today, irrespective of the manufacturer or model. With this housing, a whole new world of applications opens up for your standard SLR camera: Inside the housing you can now take the camera safely canoeing, snorkeling or even diving, up to a depth of 20 m / 60 ft.

The ewa-marine U-A 100 underwater housing is manufactured from special, double laminated PVC and has an integrated, optically neutral flat glass as a front port. With this housing you will receive an 82mm filter adapter and a RA77-82 step-up ring. By means of these adapters 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.

If the optional BF1 lead weight is inserted into the housing, underneath the camera, it becomes even easier to reach the maximum depth.

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

As off 2019, our U-A is now shipped with the new ewa-marine safety-wrist-strap. Simply slip your hand through the loop at the bottom and, if the camera accidentally falls out of your hand, the loop automatically locks and secures the underwater case to your wrist. And yet it is easy and quick to open, when required, with the integrated buckle.
