  • Easy Access to All Camera Controls
  • Optically Neutral Flat Glass Port
  • Built-in Glove for Manual Control

  • Carrying Case with Waterproof Interior

The Ewa-Marine U-BFZ100 Underwater Housing for Pro DSLR Cameras is a double-laminated PVC waterproof case that enables you to take your professional digital SLR camera beneath the surface. A derivative of Ewa-Marine's U-BF housing, it was designed especially for the pro range of DSLR's, such as the Canon EOS 1D, the Nikon D3, the Sony Alpha 900 or the Leica S, and allows for the use of longer lenses than the U-BF.

The housing is compatible with camera / lens combinations up to 9.1" (23 cm) in length, and can accommodate cameras smaller than the pro size, either with or without an additional battery pack. It has a depth rating of 32.8' (10 m), making it suitable for relatively shallow diving or shooting at or near surface level, as well as shooting around the water where you may only get splashed. Buoyancy is positive, unless you use optional weight BF1 or another comparable weight (not included), in which case it will be negative. The housing has a built-in, optically neutral flat glass port.

What differentiates the U-BFZ100 from other UB-series housings is that it has not only the finger insert for operating the camera's shutter release with your right forefinger, but also an integrated glove designed for left-handed use. The glove lets you cradle the camera and lens just as you would if it were not in the housing, which is highly conducive to manual operation for getting the precise settings desired.

The housing permits easy access to all camera controls. It comes with the CA-82 adapter to connect the camera's lens to the flat front port. The adapter features an 82mm filter thread. An RA77-82 step-up ring / filter adapter is also included, enabling you to utilize smaller 77mm diameter lenses. Simply screw the RA77-82 and CA-82 together. An optional CA-77 adapter (not included) is also available for 77mm lenses, and gets fitted to the housing's front port, like the CA-82. For lenses of a smaller diameter than 77mm, you'll need to purchase a separate filter adapter to attach the lenses to the 77mm or 82mm Ewa-Marine adapter. All lenses must have internal focusing in order to be used in this housing.

A pair of clamping rails fit together and can be tightened via 3 screw knobs to give the housing a tight, waterproof seal. These rails are seawater-resistant to ward off corrosion. A convenient yellow carrying case with a waterproof interior is supplied with the housing.

          Comments about Ewa-Marine U-BFZ100 Underwater Housing for Pro DSLR Cameras:

          I purchased an Ewa-Marine U-VFZ100 for an ocean kayaking trip, to protect my Nikon D-800E. I found the product to be badly designed, over-priced, and almost impossible to use.

          The manufacturer's website promotes their German design and engineering. Looking at the product, it seems that all of the engineering has gone into making it as inexpensive as possible to produce. My estimate of the bill of materials (BOM) cost is perhaps $20, for a housing that retails for many times that. No engineering at all seems to have gone into making the product usable.

          The housing consists of an almost flat plastic bag, to which a non-functioning bellows has been solvent-welded, with an uncoated glass window at the end. A stiff, primitive three finger glove has been solvent-welded to the bottom of the bag, and a short one-finger glove for depressing the shutter release has been solvent-welded into the upper right hand corner of the bag. A long metal clamp holds the bag shut while in use.

          There is no provision at all to hold the camera in place, so it is necessary to hold the lens in place using the glove at all times. It can take a minute or so to insert your hand into the glove, making it impossible to simply pick up the camera and take a photograph.

          Ewa-Marine supplies a couple of small pieces of foam that they suggest can be used to secure the camera in place within the enclosure. I found them to be almost useless. When the camera isn't being held, it can move both laterally and vertically, or it can rotate within the case. Any of these movements make it difficult or impossible to reach the shutter button through the short finger glove.

          The focus button can't easily be pressed through the plastic bag, so it is necessary to use the shutter release button to focus. Unless the camera is perfectly positioned within the bag, a half-press of the shutter release is difficult or impossible to execute.

          The metal clamping bar is awkward when putting the camera down, as it makes the camera tilt to the right. In this position, the force of gravity shifts the orientation of the camera within the bag, almost guaranteeing that it will be out of position the next time it is picked up.

          The optical port is prone to fogging in warm weather. The port is attached to the camera lens by a step-up ring with a small o-ring around its circumference, so the volume of air that needs to be desiccated is very small. Ewa-marine hasn't provided any way to desiccate this area, although they supply two small pouches of silica crystals, and suggest that they should be placed into the enclosure along with the camera. This doesn't work particularly well, since the volume of air that actually needs to be desiccated is separated from the main enclosure. A far better approach would have been to provide for a small amount of silica crystals inside the space between the lens and the optical port.

          It's unfortunate that Ewa-Marine doesn't have a competent design engineer, because it would't take a lot to make this a much better flexible enclosure. It seems clear that their designers are not photographers.

          Had I kept the enclosure, I would have fabricated some means for securing the camera into position. Of course, if I were to fabricate something, I would have fabricated the whole enclosure. I would have used a good quality nitrile glove for the left hand, which would have been far easier to use than Ewa-Marine's horrible three finger affair. I wouldn't have used their awkward metal clamp, with its useless strap, and I would have provided a way to keep the optical port from fogging up.

          I'd like to find something positive to say about the product. If your intention is to hold the camera at all times with both hand, while taking photographs in shallow water, the product would probably be fine.

                  I haven't submerged the housing yet, but I shot a white-water rafting TV segment with a Canon 7D and 24-105 zoom lens in it.

                  It takes some getting used to for manual focusing, but it keeps the camera dry and it is pretty much what I expected.
