SLR cameras have obvious advantages over point-and-shoot models in terms of versatility, image quality, performance, and upgradability. At the moment, however, there appears to be no waterproof SLRs. Instead, there are waterproof casings available in the market that intended to allow all brands and models of SLRs to go scuba diving.
Among them is the ewa-marine U-A Waterproof SLR Camera Case. The U-A is actually of series of waterproof cases. These vary in terms of the depth of their waterproof capabilities and in size. The U-A and U-Az models are waterproof up to 20 meters and are intended for SLRs with or without a built-in pop-up flash. The U-A is for zoom lenses up to 170mm while U-AZ can handle a 230mm. The U-AX can dive up to 20 meters carrying an SLR with a top-mounted flash. The U-AXP and U-AXP100 can go even deeper to 50 meters with an SLR and its top-mounted flash. The U-AXP100 is a special version of the U-AXP that can accommodate a lens of 77mm, 82mm filter diameter and an internal focus.
Waterproofing to the great depths is possible with the case’s double laminated PVC construction. A pair of clamping rails that are resistant to corrosion even from sea water fit together perfectly, allowing them to withstand high water pressures. Three screw knobs tighten these rails. The lens port is an optically neutral, flat, and hardened glass that eliminates distortion of images, and that allows the unhampered operation of autofocus systems and the capture of clear and sharp images.
There are great potentials for extraordinary photographs in rivers, beaches, the open seas, and, perhaps even more so, under the waters. The ewa-marine U-A Waterproof SLR Camera Case allows you to take these pictures.
