Capture vibrant images and video of sting rays, parrot fish, and coral at 200' beneath the surface with your Panasonic LUMIX ZS45 / TZ57 camera in this Ikelite Underwater Housing. External lighting is more powerful than your camera's built-in flash, but your flash can be used to trigger an optional, external AF35 Auto Flash strobe as a wireless slave, replicating TTL exposure (except when using external accessory lenses). As an alternative, two fiber-optic ports are provided for connecting optional cables. The housing also includes a diffuser to soften your built-in flash and a deflector to redirect the light towards an external strobe. This added lighting will provide greater color accuracy and vibrancy, and it can be placed in a position to virtually eliminate backscatter, glare, and hard shadows. Built for durability, the housing is designed, constructed by hand, and tested in the USA. A corrosion-resistant, clear polycarbonate and acrylic body offers a full view of the camera, allowing you to monitor the O-ring seal to ensure correct waterproof installation. Large, ergonomic mechanical controls provide access to all camera functions. The camera mounting plate features a 12-24 thread tray with 3" spacing.
