Ikelite 71473 200DL Underwater Housing for Sony Alpha A7 III, A7R III, A9 Mirrorless Cameras
The Ikelite 71473 200DL Underwater Housing is a full featured and durable waterproof housing for Sony Alpha A7 III, A7R III, and A9 Mirrorless cameras. Suitable for scuba, snorkel, surf, pool, and any application in or around the water.
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 single most important feature is the new Dry Lock (DL) port system. This exciting new system is designed to be robust and easy to assemble. It is built for reliable performance in the most remote of locations, meaning that their are no complex moving parts that may break and jeopardize your shoot. The new DL series ports are lighter and more adaptable than their FL counterparts. They accommodate popular large diameter, full-frame lenses with ease. Most popular zoom lenses and select lens focus rings can be engaged using a simple yet effective gearing system that puts adjustment right at your fingertips. Zoom and focus gears differ depending on which lens you are using. All are lightweight and affordable. Zoom gears sold separately.
This housing requires the addition of a compatible DL Lens Port for waterproof operation. Lens Port not included.
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. Use of the vacuum valve requires a compatible Vacuum Pump with Gauge # 47011, sold separately.
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 # 46042 and a compatible Ikelite DS strobe. Exposure compensation can be used added or subtracted in the camera.
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. Use the DL2 DS Link Sony TTL Converter Ikelite ST1 Hotshoe Kit # 46042 for the most accurate exposure and fastest triggering on the market. The ST1 TTL hotshoe installs quickly and easily. The TTL converter requires no batteries to weaken or die during your shoot. Only Ikelite DS strobes are capable of powering up and communicating with the TTL converter.
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 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.
Fiber optic only strobes are not compatible with this installation. An external strobe must be connected by electrical sync cord.
Strobes with remote slave capabilities may be triggered off of a flash attached to the housing by electrical sync cord. Ikelite DS strobes support remote triggering using the Optical Slave Converter # 4405 or the Water Wizard system (manufactured and sold by Aquatica).
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.
