5D M IV

Capture the beauty and variety of sea life at depths as great as 328' with your Canon EOS 5D Mark IV or III DSLR camera, thanks to the MDX-5D Mark IV Underwater Housing from Sea & Sea. Dual fiber-optic ports enable the attachment of external strobes using optional cables. As an alternative, the Optical YS Converter/C can be added on as an option, allowing for the hardwired connection and triggering of YS strobes in manual mode. The MDX-5D Mark IV also accepts an optional 2-pin sync cord connector as another means of hardwired manual strobe triggering.

The convenient quick shoe makes it easy to install and remove the camera. Mechanical controls provide access to virtually all camera functions. With both hands on the ergonomic grips, you can easily reach important controls like the ISO, AF point selection, and Multi-function selection levers. The housing includes an optical viewfinder offering 0.5x magnification, and is also compatible with two optional 1.2x OVFs and a 0.8x OVF.

Built for durability, the MDX-5D Mark IV is made from an aluminum alloy that's been treated with an anodized finish to resist corrosion. A supplied moisture alarm senses when a breach occurs in the housing's waterproof seal and notifies you immediately. The housing ships without a required lens port, and accepts a system of interchangeable ports for a broad array of different lenses. For compatibility, see the System Chart.
