ewa-marine U-BXP100

Underwater housing for consumer SLR cameras

order code: U-BXP100

The 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 U-BXP100 is a special version of the ewa-marine U-BXP underwater camera housing designed to accommodate SLR cameras with larger diameter lenses than the standard version and can be used with lenses that have a 77mm or 82mm filter thread. It 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 50m / 150ft.

The housing will accept all lenses with a filter thread of 82mm (with the optional CA82 adapter) or less. It comes, out of the box, with an adapter for 82mm and a step-up adapter RA77-82 for 77mm filter thread. Depending on the lens, you should be able to use the housing with focal lengths of around 18mm to 19mm for a full-frame sensor camera. Using wider angle will result in vignetting, i.e. the corners of the picture getting dark an, if going even wider, the picture being taken "trough a tunnel". Naturally, this effect does not apply for cameras with a smaller sensor like APS-C, were vignetting would only start at more extreme wide angle settings and with lenses that do not have a filter thread and can therefore not be used in the housing.

If the optional BF1 lead weight is inserted into the housing, underneath the camera, it becomes even easier to reach the maximum depth. Experienced photographers have confirmed, that the auto focus and flash both continue to function perfectly. As you descend, the air is pressed into the camera. Due to this, the pressure inside the housing will remain the same as the surrounding water pressure. (this is the reason why ewa-marine housings are so safe to use: implosions are impossible) Due to this, we have to start the dive with a suitable amount of air inside the housing. The foam pads supplied with the housing are part of this air "reservoir" and additional air should also be blown into the housing, via the valve at the rear, to ensure that the maximum potential volume is being utilized.

This is only one of a range of underwater SLR housings by ewa-marine.

Click, if you need help to find the right housing for your camera, lens and application.

The housing has a wider front glass than the U-BXP and allows in combination with the C-A82 adapter and step-up adapter RA77-82 (supplied with the housing) the use of lenses with a filter thread of 77mm and 82mm. This enables you to use wideangel lenses with a focal length of 17mm without problems.

Depending on your application but the following products offer a better solution:

  • U-B: Compact without a top mounted flash gun ideal for snorkeling
  • U-B100: Similar to the U-B, but with a larger front port to allow the use of lenses with 77m or 82mm filter thread
  • U-BXP: SLR with top mounted strobe and a lens with up to 72mm filter thread. Up to to 50m / 150ft dive depth. Primarily for scuba diving.
  • U-BZ100: For outdoor photography while canoeing or kayaking with long zoom lenses

Designed specifically for consumer style digital dSLR, large mirrorless system-camera as well as the "old style" analog 35mm SLR cameras, the ewa-marine U-BXP100 underwater housing is manufactured from our 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 adapter. By means of these adapters the camera is then docked into the housings front port (which is bigger on this housing then on the standard U-BXP), ensuring that the lens remains parallel and centered behind the front of the lens. Just as if it were a clear, neutral optical filter.

The external flash that is commonly used on SLR cameras fits into the specially designed section on the top of the housing. To fix the right hand near the shutter release, the housing has an adjustable wrist strap and a "Finger" to position the index finger right on the trigger.

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.

Actually, it's not in a box at all. We sell this unit in a handy, yellow, nylon carry bag. This bag is ideal to store and transport your ewa-marine housing, it also helps reduce unnecessary packaging-waste and as such is part of our amain to help the environment.

  • C-A 82 special adapter *
  • RA77-82 step-up adapter *
