This Underwater Housing from Ikelite is a waterproof case enabling you to shoot beneath the water's surface with your Nikon D7100 DSLR camera. It has a depth rating of 200'.
The housing provides access to all important camera functions via mechanical controls. The case is constructed from durable, corrosion-resistant polycarbonate, which is clear to enable you to monitor the O-ring seal and camera. Housing buoyancy is slightly negative in freshwater. A compatible lens port from Ikelite's Standard or Modular system is required and sold separately. Ports are available for most popular lenses. See Port Chart and Port Finder.
Though the camera's built-in flash is not usable, the housing supports electrical TTL flash exposure with optional external Ikelite DS Substrobes--without requiring the camera's built-in flash to fire. This gives you extended battery life and reduces or eliminates lag time between exposures. The electrical bulkhead and TTL circuitry for direct strobe connection are provided standard on the housing. Non-Ikelite strobes can also be used, but will provide manual exposure only (not TTL).
The housing features a glass optical viewfinder and includes a tray with comfortable rubber grips, as well as a set of lens zoom gears.
