The Ewa-Marine U-BXP100 housing is specially designed to fit the bulky, professional digital SLR cameras such as the Canon 1Ds or the Nikon D2X, D200 and similar cameras. Smaller SLR cameras can still be used in the housing. The housing is manufactured from double laminated PVC and has an optical glass port. It is rated for dives of up to 155' (50 m) depth.

Perfect for snorkeling, diving, sandy, dusty, humidity or foul weather conditions. This housing will give your camera the best possible protection while being fully operable.

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

It has a pair of non-corrosive and seawater resistant clamping rails which fit together for sealing. They tighten by means of screw knobs. The external flash that is commonly used on SLR cameras fits into the specially designed section on the top of the housing.

This housing accommodates a maximum 82mm lens filter size, and comes supplied with a threaded 77mm lens-to-port adapter ring. An optional 82mm adapter is also available (#CA82).This allows wide-angle lenses to be used with this housing. All lenses used with this housing must have internal focus.

Do you need to buy a step up ring to fasten each lens to the front glass? It's unclear to me what the step-up rings are for...
Asked by: jacqueline
You need to use a CA adapter to keep the lens in the center of the Ewa-Marine U-BXP100 Underwater Housing's lens port. The housing includes the Ewa-Marine C-A77 77mm Adapter Ring Set for lenses with 77mm filter threads. If the lens you are using has smaller threads you will need to use a step-up ring.

question

The specs says we can use 16mm lenses on a full frame body with this housing, but the manufacturer's website says we should experience vignetting at 19mm or wider. So, using 16mm on a full frame it's not possible, right?
Asked by: Douglas T.
any lens shooting underwater will result in some vignetting, but the wider the lens is you will have to crop some. but it will work in that housing.

question

What's the maximum focal can be used without vignette ? I use Sony A7RII with 16-35 most of time and wider lens like ( 12mm 15mm ). Is it possible to use with this housing ?
Asked by: Anonymous
Hi Dziung, there will always be vignetting of some sort while shooting underwater, but the limits on lenses in this housing are really the filter thread size (max is 82 mm) we recommend the widest possible settings to be used and framing where crops are possible. Hope this helps. All the best, Eric

question

does it have a protection glass on the housing for the lens?
Asked by: Anonymous
Yes, the see through element in front of the lens is made of glass. There is also a metal ring that attaches to the lens itself and helps a more snug fit between the front of the lens and the glass.
