Ewa-Marine U-BXP100 overview

  • 1Description

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.

    Ewa-Marine U-BXP100 reviews

    U-BXP100 Underwater Housing is rated 3.7 out of 5 by 18.
    Rated 4 out of 5 by from Great protection but awkward to use. I bought this product to protect an expensive dslr from ocean wave splash and it absolutely does that and more. I tried it snorkeling and while it protected the camera it was way too buoyant (though you could add weight) and hard to get to the controls. I would not take it diving for the same reasons. When using it, you can set up the camera to make the use easier but it is really hard to manipulate the controls thru the plastic. I was also chagrined to find that there is no way to attach it to a tripod. Also, be sure you have the correct lens rings. It came with a 77mm but the best fit was with my 24-85mm lens that has a 72mm filter ring.

    Rated 3 out of 5 by from More difficult than I thought Once you get over the fact you just paid over 4XX dollars for a plastic bag, it does allow you to take underwater pictures, although without much customization, at least on the spot. As other have pointed, it is best to set the camera settings before going in the water. Me using the Canon 7D,20D, it was almost impossible to change settings via the dial wheel (both of them)and even adjusting zoom range on the lens was with difficulty. What separates this model/brand is that it keeps the front glass attached to the lens which is great, because it eliminates vignetting. If you can't afford the hard housings, like me, then this is the best option available.

    Rated 4 out of 5 by from Reasonable for cost Like all the reviews, controls are hard to operate. A bit of guesswork to know what settings to set your camera to on the surface, especially as a noobie. Experience will minimize this. Camera stays dry. Even with all the air taken out (when not using a flash), it still bobs like a cork. A bit cumbersome when using a scuba mask, and spinning the dial is work. Main advantage to a hard case here is if you switch camera bodies, you can still use this housing. And it lets you use flash, or even remote triggers for strobes above water (great for strobing into a swimming pool) For the price, I can't complain too much, the only way you'll get easier use of controls is to buy a hard case, and that means $1500 minimum for a pro DSLR (and you're stuck if you upgrade bodies in the future). For simple surf shots, portraits around a pool and basic underwater shots, this is great. For serious SCUBA imaging, not so much.

    Rated 5 out of 5 by from 'Inexpensive' functional alternative The Ewa-Marine U-BXP100 is an 'inexpensive' solution for shallow water photography compared to diving equipment. But you get what you pay for. You can not effectively make any adjustments to the camera once it's inside the unit. Moreso, I could not feel the shutter release button through the finger sleeve and could only tell I had taken a photo by the mirror and shutter movement through the body itself. But the camera survived and the photos look pretty good. I can take my digital SLR underwater and reap the benefits of faster focus over a waterproof point and shoot.

    Rated 3 out of 5 by from decent for the price My major problem with this was that it did not come with any directions or instructions. It is solidly made but I had a heck of a time figuring out how to get the camera in and make sure it is sealed.

    Rated 3 out of 5 by from About what you'd expect ... from a pvc bag. Used this with a 5D II, snorkeling a couple times and on an all day sea kayak tour. Had a 24-70mm Canon lens on and was difficult to pull the lens out to 24mm; the elasticity in the pvc made that difficult. And would not stay at 24mm unless you pulled and held it there which is very awkward. Controls were fairly useable with careful attention; not on the fly. Lens adaptor friction fits into housing lens (that was not clear to me on research). Buoyancy is definitely a problem if you want to go down but I did not play with the air release valve as I was on the surface mostly anyway. Seems absurdly expensive but got the market cornered. I'm very concerned about bend and fold points developing cracks or holes quickly but don't see much about that in reviews. Don't get the strap system at all. I guess its just a carry strap with extra loop at bottom for diving weights. Wish they had explained that in their product info. I need something with a harness to strap to chest. I expect it to be valuable for river rafting photos, especially if I can retrofit the harness.

    Rated 5 out of 5 by from Great for underwater photography on a budget This is great for travel and people who are not wanting to spend their life savings. However, you will have to pre set your camera and pray you don't hit any buttons putting it in the bag. Also I find the finger hole for the shutter to be more trouble than it's worth and just press from the outside of the bag. Those two things are probably the worst it gets honestly. It's a great product and it is my first underwater case and I love it. Just make sure YOU have your settings correct and do your research and you'll get a great shot.

    Rated 2 out of 5 by from meh Being too cheap to buy an Ikolite or similar case that would allow full functionality I rolled the dice with this one figuring that as long as it keeps the camera dry then I would figure out a way to make it work. Well... I wish it were that easy. The case certainly keeps an SLR dry, however I didn't buy an SLR to put on auto. Adjusting controls through the bag is near impossible, honestly even pressing the shutter is more annoying than I hoped. Another main reason for my disappointment is that my widest lenses are the 15mm Canon fisheye (which doesn't work b/c it can't secure to the lens housing) and then Canon's 24-70mm f/2.8 L lens. Before making the purchase I knew the fisheye wouldn't work but I clearly didn't give enough thought to the 24-70mm. That lens is wide when the barrel extends forward. Unfortunately there's really not enough room, so the accordion-like lens housing wants to shrink back into shape causing you to shoot at around 50-60mm. Annoying as all heck when you realize that there's no easy way to put your hands on the lens, you resort to grabbing the front black ring on the lens housing and pulling and holding the lens out in order to get the wide angle shot. Thankfully, I've wanted and plan on purchasing the 17-40mm f/4 L lens soon, but I still can't help but feel disappointed in this case. I grew up in love with the water and have taken many pictures of surfers and riding waves my self with underwater point and click cameras however I thought this might be a good way to start with my SLR. Fed up with the frustration of still photography when using this case, I resort to taking video in this bag using my 5d Mark II. I'd love to sell it used. I want to spend the extra dough and get an Ikolite or at least do more research and get something worthwhile. On the plus side you have limited control over the amount of air in the bag so you can better adjust bouyancy.
