This Outex Underwater Camera Cover Kit from B&H comes with everything you need to use most compact or mirrorless cameras underwater or in challenging conditions like driving rain or blowing sand. The kit includes a 120mm dome port which corrects the magnification caused by underwater refraction for close-up use of wide-angle lenses. The dome is also ideal for split level shots (over and under the surface). The small-sized silicone camera cover measures 5.9" wide, 4.9" high, and 9.4" from the back of camera to the front of lens. The kit also includes an adapter for attaching the dome port to an 82mm-diameter lens, wrist and neck straps, and the harness to which the straps attach.
