This Underwater Housing from Ikelite is a waterproof case enabling you to shoot beneath the surface with your Canon Power Shot SX280 HS digital camera. It has a depth rating of 200'. The housing provides access to all camera functions via mechanical controls and enables the use of the camera's built-in flash. Built for durability, it is constructed by hand in the USA from durable, corrosion-resistant polycarbonate, which is clear to allow you to monitor the O-ring seal and maintain a full view of the camera. The housing's flat glass port accommodates the camera's lens, and also accepts external wide-angle and macro accessory lenses. The wide-angle option is the WD-4 dome, which simply slides onto the front of the port. For close-up shooting, attach virtually any macro add-on lens with standard 67mm threads. Expand your system by adding an optional AF35 Auto Flash strobe, which features a flex arm and mounts onto the grip handle of an optional tray. This external strobe is triggered as a slave by the firing of the camera's built-in flash and replicates TTL exposure. The housing comes bundled with a flash diffuser to soften the light of the camera's built-in flash and a flash deflector to redirect it towards an external strobe.
