The housing can be used on small boats, in the surf, while swimming, snorkling or diving. As the camera and its various components are be operated through the plastic, the camras is operated normally and the use of an ewa-marine housing is easily adapetd to by the camera man.
The U-AX is designed to fit almast all common SLR cameras on the market today, irrespective of the manufacturer or model. With this housing, a whole new world of applications openes up for your standard SLR camera: Inside the housing you can now take the camera safely canoeing, snorkling or eaven diving, up to a deapth of 20 m / 60 ft.
If the optional BF1 lead weight is inserted into the housig, underneath the camera, it becomes even easier to reach the maximum depth. Experienced photographers have confirmed, that the auto focus and flash both continue 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 potential volume is being ut¹lised.
Designed specifically for 35mm SLR cameras, the U-AX housing is manufactured from double laminated PVC and has an integrated, optically neutral flat glass port. The external flash that is commonly used on SLR cameras fits into the specially designed section on the top of the housing.
It has a pair of non-corrosive and seawater resistant clamping rails which fit together for perfect sealing. They tighten by means of three screw knobs.
It is supplied in a handy yellow carry-case which has a water-proof interior and zippered side-pocket.

This is a great sturdy bag that I would take underwater anytime - on auto mode that is. The biggest drawback is that you really cannot turn the rings on your lens: 'very little' with bare dry hands and 'not at all' underwater (wet hands or scuba gloves on). I actually read before I bought it, that the lens part of the bag ROTATES with the lens - not true, the bag is one piece. It extends great! All other controls on the camera are very hard to operate. I like using my camera on Manual, so this is a big inconvenience for me. However I rather use my camera on auto, in this bag, then a underwater compact camera. The fit is not snug at all, if that is an issue for you, for me it seems harder to operate the camera with all the loose material around it. The little screen on the back doesn't match the camera display, so it's rather in the way. Another problem I have with it, is the closure system: it seems great but there is no backup. I think it should be a secondary fold or ziplock type closure, just in case. A bit pricey. Now the pros: It accommodates the flash which is really a lifesaver in the harsh direct light of a pool, or in the low-light situations of scuba diving. The lens front seems wide (plenty for a 67) and clear enough, assuming there are no scratches. I have not tested it at the maximum depth yet. If I were to change anything, -I'd l-o-v-e to see the lens compartment actually rotate along with your lens; -back-up secondary closure system; -maybe have a finger compartment (or maybe extra texture on the inside, for easier controlling exposure etc. (unfortunately it has to be camera-specific); -no screen on the back OR a bigger one; -better buoyancy compensation; -lower price. All in all, a pretty good alternative for a must-have uw casing.
