Built for durability, the housing is constructed from precision-machined aluminum that has been anodized for resistance to corrosion. The housing is designed with a buoyancy pocket that reduces its weight under water or can accommodate a mobile battery charger for more shooting time. A built-in leak sensor alerts you immediately in the unlikely event of a breach in the waterproof seal.

The MDXL-a7IV ships without a required lens port, and accepts a series of interchangeable ports for various lenses. For compatibility details, see the Port Chart. The housing ships with the 0.5x optical viewfinder, but optional 0.66x, 0.8x, VF45, and VF180 viewfinders can be added on to enhance your view for better shot composition underwater.
