The Canon WP-DC52 Waterproof Case is a durable underwater housing for your PowerShot G16 digital camera. It has a depth rating of 131'. Mechanical controls provide access to all camera functions. The case is constructed from clear polycarbonate and has an integrated flat glass lens port with an anti-reflective coating on both sides. It comes configured with a cold shoe for mounting accessories. The camera's built-in pop-up flash is usable within the WP-DC52, which includes a flash diffuser to soften the light of the flash, thus preventing harsh light from causing glare, backscatter and hard shadows. Additionally, you can connect an optional fiber optic cable for an external strobe via the included attachment.
