The camera mount is front-loading for easy installation and removal. A small mounting plate attaches to the bottom of the camera and secures in the front of the housing. The camera mounting plate does not need to be removed from the camera for surface use or when changing the battery or memory cards. The mounting plate features a 1/4-20 threaded mount on the bottom so that it can be attached to a tripod on the surface.

The unique rear seal design prevents accidental twisting or stretching of the o-ring for simple and confident assembly. We have eliminated the need for an o-ring groove or channel which can trap sand, dirt, or debris. Two double-passivated stainless steel locking lid snaps are simple to use and virtually unbreakable. The clear back allows you to see the o-ring form a solid, watertight seal as it closes.

Vacuum Testing
A spare 1/2-20 threaded accessory port is provided on the side of the housing for easily installation of the optional Vacuum Kit # 47012. A vacuum kit allows you to draw a vacuum on the housing to check for leaks prior to entering the water.

Drawing a vacuum on the system also provides extra security at the surface of the water, especially important when using the housing in rough surf.

Viewfinders
The camera's large, super-bright LCD screen is viewable edge-to-edge through the back of the housing. An included optical viewfinder window blocks ambient light to improve viewing of the camera's electronic viewfinder (EVF) for both image composition and review.

Get the brightest and sharpest view of the camera's OLED EVF by adding an optional Magnified Viewfinder. The Supereye removes quickly and easily for the attachment of a Straight Enhanced Magnified Viewfinder # 6890.2 or 45° Magnified Viewfinder (Type 3) # 6891.3.

Lighting
Light is absorbed as it travels through even short distances underwater, making colors appear dull or monochromatic. To preserve the natural colors of your subject, it's important to stay within arm's reach—no more than 3-4 feet (1m) away. For the best results, we recommend adding an external flash or high-powered constant-on light if you'll be diving regularly below 15' (3m).

You can enjoy the fastest and most accurate TTL exposure on the market by adding the DL3 DS Link TTL Converter and Hotshoe Kit # 46032 and a compatible Ikelite DS strobe. Rear curtain flash synchronization is supported. Exposure compensation can be used added or subtracted in the camera.

Reliable locking connectors between the hotshoe and bulkhead make it easy to install the TTL hotshoe or carry back up parts when traveling to remote locations.

This camera does not feature a built-in flash for the triggering of fiber optic strobes.

A bright constant-on video light can be used instead of or in addition to a flash. A constant-on light is not as bright as a strobe flash. Constant-on lights do provide added versatility because they can be used for focus assist and for improved colors when shooting video.

There is a simple rule that brighter is better underwater. A high-quality lighting system can produce professional quality results.

Port System
It couldn't be more simple to change ports than this system—just press the port on and tighten three thumb screws. Feel positive reinforcement that the port is secure with simple parts you can trust in a remote location.

This housing accepts ports from our DLM Port System to accommodate a selection of the best zoom, macro, and wide angle lenses for underwater use. Our custom optical grade acrylic domes components provide the color, clarity, and durability of glass at a fraction of the travel weight and cost.
