The Ewa-Marine U-B 100 housing is specially designed to fit bulky, digital SLR cameras such as the Canon 1Ds, Nikon D3, D300 and other cameras around the same size. Smaller SLR cameras can still be used in the housing. The housing is manufactured from double-laminated PVC and has an optical glass port.

The lens port is wide in order to accommodate lenses with a large diameter. Use the included C-A 77 adapter for lenses with a 77mm filter thread or the C-A 82 adapter for lenses with an 82mm filter thread. All lenses used with this housing must have internal focus.

Perfect for snorkeling, diving or for use in sandy, dusty, humid or foul weather conditions. This housing will give your camera the best possible protection while being fully operable. The housing is perfect for canoeists and other outdoor photographers that want to take pictures of wildlife while in or near the water.

If the optional BF1 lead weight is inserted, underneath the camera, it becomes even easier to reach the maximum depth of 60'. The auto focus of the camera continues 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, you must 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 volume is being utilized.

The housing has a pair of non-corrosive and seawater-resistant clamping rails which fit together for sealing. They tighten by means of screw knobs. This housing accommodates a maximum 82mm lens filter thread. The lens could be as long as 7.87" (200mm).

question

So does this come with the 77mm adaptor? It says so in the specs, but the header says it's for 82mm??
Asked by: Rod N.
The 77mm ring is included (or at least it was when I purchased mine). You can use it with an 82mm lens with an adaptor which can be purchased separately. You can read my review on my website, My Irie Time.

question

Will the 24-70mm nikorr fit and work well in this housing? Do i need to buy extra accessories to accommodate it? Note: I'm not going to put a filter on my lens while using it underwater.
Asked by: Nasrin S.
I am not familiar intimitely with that lens, so my apologies, if the lens takes a 77mm filter then the included c-a77 adapter will work, if the lens takes an 82mm filter then you will need to purchase the C-A82 adapter. hope this helps.

question

Can this system work witr Canon 5D Mark III with 24-70 f/2.8? Does anyone have an experience with this set up? Thank you!
Asked by: Nicholas P.
It does but you have to tape the lens or the zoom will will get pushed to 24mm. Apparently theres a tool you can mount on the lens that holds the accordion lens portion of the bag away from the lens so it doesn't get pushed back, but I haven't found it. Let me know if you do.
