The housing

DL ports are the lightest on the market, yet robust and capable of standing up to rough surf. Attachment is quick and secure. A system of extensions can accommodate a huge variety of lenses with ease. Most popular zoom lenses and select lens focus rings can be engaged using simple gearing that puts adjustment right at your fingertips. A vacuum valve is installed standard on the side of the housing. The vacuum valve is designed to be low profile to avoid interference with controls. The optional Vacuum Pump with Gauge #IK47011 allows you to draw a vacuum on the housing to check for leaks prior to entering the water and a spare M16 threaded accessory port provides an attachment point for third party accessories including HDMI bulkheads.

TTL Exposure/Strobes

This housings supports your choice of shooting with manual strobe exposure or adding a TTL converter depending on your application. The flash bulkhead is located on the top of the case to alleviate strain on the sync cord. You can enjoy the fastest and most accurate TTL exposure on the market by adding the DL2 DS Link Sony TTL Converter Ikelite ST1 Hotshoe Kit #IK46042 and a compatible Ikelite DS strobe.
SEA&SEA, INON, and Retra strobes with an electrical connection can be triggered in manual exposure modes using an electrical sync cord. Strobes without an electrical sync cord connection cannot be attached to this system unless slaved off of a hard-wired strobe. The included SuperEye Viewfinder provides an enhanced view of the camera's electronic viewfinder when viewed through a dive mask. The viewfinder removes quickly and easily for the attachment of an optional Straight Magnified Viewfinder #IK6890.2 or 45° Magnified Viewfinder (Type 1) #IK6891.1
