Ewa-Marine U-BF100 overview

  • 1Description

The Ewa-Marine U-BF100 Housing was specially designed for large digital SLRs such as the Canon EOS 1D, the Nikon D3, or Sony Alpha 900, with lenses that have a filter thread up to 82mm. The housing will also accommodate smaller SLR cameras with a battery pack. It is manufactured from double laminated PVC and has an optical glass port. A pair of non-corrosive, seawater resistant clamping rails fit together to keep your camera safe and dry down to 33' (10m). The U-BF100 comes with a glove integrated into the housing, so your left hand has access to the lens. All camera controls are accessed through the PVC.

This housing is ideal for working in or near water close to the surface. The housing accommodates autofocus SLR cameras without shoe-mounted strobes, with maximum dimensions of 9 x 9 x 5" (228.6 x 228.6 x 127mm), with lenses that have a maximum filter thread of 82mm. Keep in mind only internal focus lenses can be used with this housing. The housing is shipped with an Ewa-Marine 82mm adapter to connect the camera's lens to the port. For smaller lenses a RA77-82 is also included.

An Ideal Near-the-Surface Solution
This Ewa-Marine housing is perfect for use at or near the water's surface, such as in sailing or snorkeling, but is also practical for protection from harsh weather conditions

Long-lasting housing solution that is easy to maintain and packs in minimal space
Non-Corrosive Clamping Rails

    Ewa-Marine U-BF100 reviews

    U-BF100 Underwater Housing is rated 3.5 out of 5 by 2.
    Rated 3 out of 5 by from OK above water Saw this product advertised in photo journal and though it would be good for working with pro camera above and slightly below surface of water. However, 1) instructions provided did not match product, 2) attachment ring (82 mm) friction fits into glass lens port so that when camera/housing taken just below surface of water, glass port pops off and vignetting occurs. Need to remember to keep pressure on outer port housing so this doesn't happen! Otherwise works nicely in keeping water from camera. Limited range of lenses that can be used with pro camera (D3)- 24-70 lens doesn't fit. Can use 50 mm and smaller and likely can use anything shorter than the 24-70mm zoom.

    Rated 4 out of 5 by from It works! I read many reviews on this product before purchasing it. I did not want to spend more than 2k on a better one just to use a few times. Here are my details in random order: Swimming pool. This was a 1st time trial with my best friend to prepare for a fashion shoot next week. Canon mark ii 5d w/battery grip. I had to remove the battery grip to fit it in the housing. You can put the battery grip back on after you get the camera in the housing. 24-105 f/4...this is the only lens I own that would have fit in the housing AND used the adapter rings that come with it - these rings keep the lens glass flush with the housing glass. You must wear goggles to see what you are doing - duh! At first, it was very difficult to stay still underwater because the little bit of air in the housing surprisingly makes the camera float with a force that makes you fight it down. Next time, I will have a weight for the camera and possibly myself. I was manually focusing and the camera did a pretty good job doing that. The adapter rings made a vignette on one edge of the photo that I did not want, so I shot very wide so I could crop. This half-vignette could have actually been the outside ring of the housing, so maybe I should have slowed down to readjust the lens position. I did not do much zooming. It was difficult, but possible to change camera settings. I purchased this for an underwater fashion shoot in a pool. If you are looking for the least expensive means to get your nice dslr underwater and take pictures, this is it. It is scary at first and cumbersome, but it works.
