Underwater housing for professional dSLR cameras
order code: U-B100
The U-B100 SLR 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 U-B100 is designed to fit almost all common, professional SLR cameras on the market today, irrespective of the manufacturer or model. It is designed primarilyfor the use with larger diameter lenses with a 77mm or 82mm filter thread.
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 housing will accept all lenses with a filter thread of 82mm or less. It comes, out of the box, with an adapter for 82mm filter thread and a step-up ring 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" to ensure that the maximum potential volume is being utilized.
This is only one of a range of underwater SLR housings by ewa-marime.

The U-B100 is a practical, "all-round" housing that is primarily intended the be used while swimming, snorkeling and other, general water sports. While it can also be used for scuba diving, for lack of a strong, external strobe, and because the camera's small, built in flash is to close to the lens, resulting in small, suspended particles in the water showing as "snowflakes" in the picture, i.e. can not be used in most applications, the U-B100 is limited to 20m / 60ft. A depth where you also can still take pictures with ambient, natural light. Since underwater photography generally requires the use of wide angle or macro lenses and thus shorter lenses, the lens tubes on the housing is kept rather short.
Depending on your application but the following products offer a better solution:
- U-B: For camera lens combinations where the lens has a filter thread of 67mm or smaller
- U BXP: SLR with top mounted strobe and up to to 50m / 150ft dive depth. Primarily for for scuba diving.
- U BXP100: Similar as the U-BXP but with camera lens combinations where the lens diameter is too large for the standard unit. i.e. filter thread 72mm, 77mm or 82mm
- U-BZ100: For outdoor photography while canoeing or kayaking with long zoom lenses
Designed specifically for professional, digital dSLR cameras, the ewa-marine U-B100 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 step-up adapter RA77-82. 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-B), ensuring that the lens remains parallel and centered behind the front of the lens. Just as if it were a clear, neutral optical filter.
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.
It is supplied in a handy yellow storage and carrying case.
|Length inkl. lens||185 mm|
|Diameter Frontglass||95 mm|
|Max. Filter thread diameter lens||77/ 82 mm|
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.
In Addition to your housing and closing rail you will get the following with your new ewa-marine:
- CA-82 Adapter *
- step-up adapter RA77-82 *
