Ikelite 200DL housing Sony A7III, A7RIII, A9 #71473

Shown with lens port (not included). A lens port must be purchased separately for waterproof operation. 
The  Sony A7III, A7RIII, A9 are sliding into the form fitting housing using a simple tripod-style attachment. Controls are provided for all important camera functions and positioned intuitively to take advantage of the muscle memory you develop when using the camera on the surface. A unique universal gearing system puts zoom or focus at the tip of your finger with a brand new soft-touch, 5-lobed knob. The new white ABS-PC blend is specially formulated for added strength and durability. Compared to black, colored, or clear alternatives, the white shell keeps the camera running cooler, longer in hot, sunny climates.

This housing features the new DL (Dry lock Port system). It adds security at the surface of the water and accommodates large diameter lenses. Ikelite also offers a special 50 feet / 15 meter version and if you are not quite ready for the DL port system a version with the traditional four port locks.

Construction
The new white ABS-PC blend front is stronger than its clear counterpart, provides improved contrast and visibility, and keeps your camera running cooler in the sun. This material is 1/3 of the specific gravity of aluminum, making the housing much lighter and fundamentally corrosion free.

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.

A spare 1/2-20 threaded accessory port is included on the top of the housing near the bulkhead for expansion to future uses.

Like all of our housings, this product is made in the USA, individually inspected for fit, and water pressure tested to 200 feet (60m).

Rear view
The clear acrylic back provides a full view of the camera, o-ring, LCD screen. The camera's Access Lamp is visible through the back. The LCD monitor may be tilted during installation for a better viewing angle underwater.

TTL Exposure
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 ST1K TTL Kit for Sony Alpha # 46040 and a compatible Ikelite DS strobe. 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 optional ST1K TTL Kit for Sony Alpha or carry back up parts when traveling to remote locations.

Ikelite DS Strobes
Ikelite DS series strobes can be used in manual exposure modes when attached directly to the housing using Single Sync Cord # 45151 or Dual Sync Cord # 45152. Install the ST1K Sony Alpha TTL Kit # 46040 for the most accurate exposure and fastest triggering on the market. The TTL Kit installs quickly and easily and requires no batteries to weaken or die during your shoot. Only Ikelite DS strobes are capable of powering up and communicating with the TTL Kit.

Ikelite Non-Digital Strobes
Older non-digital strobes featuring an ICS-5 electrical sync cord bulkhead can be used with this system in manual exposure modes.

SEA&SEA, INON, or Retra Strobes
SEA&SEA, INON, or Retra strobes with an electrical connection can be triggered in manual exposure modes using Single Sync Cord # 45281 or Dual Sync Cord # 45282. Strobes without an electrical sync cord connection cannot be attached to this system unless slaved off of a hard-wired strobe.

Vacuum system
The included vacuum valve allows you to vacuum test the housing to check for leaks prior to putting your expensive equipment in the water. Combined with a full view of the camera and o-ring seal through the back of the housing, there is no greater assurance that your gear will be safe. Our signature open-groove design suspends the rear o-ring in a natural position that is easier to maintain and more reliable than forcing the o-ring into a channel.

Use of the vacuum valve requires a compatible Vacuum Pump with Gauge # 47011, sold separately.
