Capture brilliant images of the aquatic world with your Sony Alpha 1 or a7S III mirrorless camera in Ikelite's 200DL Underwater Housing with Dry Lock Port Mount, which has a depth rating of 200'. An Ikelite bulkhead with a manual hot shoe connection enables reliable electrical triggering of optional external strobes via sync cords. The use of an optional TTL hot shoe and converter will allow for TTL operation with compatible Ikelite DS strobes; non-Ikelite strobes will still work in manual mode only.

Ergonomic, mechanical push buttons, dials, and levers afford access to all important camera functions. Built for durability, the enclosure is made in the USA from a corrosion-resistant ABS plastic and polycarbonate blend. It is white on the front, top, sides, and bottom, but clear in the back to allow you to monitor the O-ring seal and maintain your view of the camera's rear controls. The supplied aluminum tray with a left-hand quick release grip affords improved balance and handling while offering an attachment point for an optional lighting arm.

This housing ships without a required lens port and accepts various, interchangeable dome and flat ports for an array of lenses. For complete compatibility information, see the port chart. The Dry Lock (DL) port system accommodates lenses with large diameters, and it provides added security against leaks at the surface, thanks in large part to the included vacuum valve for checking watertight integrity before the dive. You'll need to pick up the required pump to remove excess air and create a vacuum.
