Underwater housing for large, professional style dSLR cameras
order code: U-BZ100
The U-BZ100 is a special version of the U-BZ housing.
It has a wider frontglass and allows in combination with the C-A 77 adapter (supplied with the housing) and C-A 82 (available as an accessory from your dealer) adapter the use of lenses with a filter thread of 77 and 82mm.
This means you can use your professional digital SLR camera like the Nikon D300, D800, D3, D4 und Canon 5D Mark II, 5D Mark III, EOS 1DX and similar cameras, with most of the professional zoom lenses currently on the market.
The fact that the U-BZ 100 can be used with up to 300m lenses, makes it specifically interesting for canoeists and other outdoor photographers that want to take pictures of birds and other wild life while in or on the water.
Please note: All lenses used with this housing must have an internal focus.
Lenses with a smaller filter diameter can also be used in this housing as long as they have an internal focus. You just need the right step-up ring.
The autofocus adapter (AV110) is not included in delivery as it is not needed for this housing.
If the optional BF1 lead weight is inserted into the housing, underneath the camera, it becomes even easier to reach the maximum depth of 20 m / 60 ft. Experienced photographers have confirmed, that the auto focus 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.
The U-BZ100 is specifically designed for cameras with longer lenses what makes it interesting for canoeists and out door photographers. While it can also be used for scuba diving, for lack of a strong, external strobe. The camera's small, built in flash (if available at all) 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-BZ100 is limited to 20m / 60ft. A depth where you also can still take pictures with ambient, natural light.
Depending on your application but the following products offer a better solution:
- U-B100: Similar to the U-BZ100, but with a shorter front port tubus. Ideal for short lenses (wide angle and fixed focal length)
- U-B: Similar to the U-B100 but with a smaller front port diameter allowing a maximum 72mm filter thread (and a bit cheaper)
- U-BXP100: large dSLR with top mounted strobe and up to to 50m / 150ft dive depth. Primarily for for scuba diving.
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-BZ100 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 77mm filter adapter (a 82mm adapter is available as an optional extra). By means of this adapter the camera is then docked into the housings front port (which is bigger on this housing then on the standard U-AXP), ensuring that the lens remains parallel and centered behind the front of the lens. Just as if it were a clear, neutral optical filter.
As many cameras in this category have a built in, pop-up flash we have added a "roof" to accommodate it in 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.
It is supplied in a handy yellow storage and carrying case.
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-77 Adapter
- sachet of Camera-Dry silica-gel
- foam padding (can be removed to accommodate battery grip or weights)
