Ikelite Underwater Housing for Sony A7, A7S, and A7R (6843.71)
Full-frame, low-light performance in a small package.
True Sony TTL
When your subject is quickly approaching, you'll be glad to have the only housing that provides TTL support for Alpha 7 cameras. An integrated TTL circuit features model-specific encoding, which has been fine-tuned to Sony's latest flash exposure protocol. The circuit is powered by the strobe for zero maintenance and no batteries to change. Exposure compensation in TTL mode is supported using the camera's built-in control. At this time, only Ikelite DS strobes are capable of powering the circuitry. SEA&SEA, INON, and Nikonos strobes will still enjoy fast recycle times and improved battery life, but must be used in manual exposure modes only.
A fast and reliable strobe connection is essential to getting the shot underwater. This housing provides a direct electrical connection to the camera's external flash hot shoe. The bulkhead connection has been moved to the top of the housing to keep cords out of your way and reduce strain on the cord ends.
The Lens Support You Want
It couldn't be faster to change ports than this system—just press the port on and snap the four locks closed. This housing accepts a variety of ports to accommodate all of the most popular zoom, macro, and wide angle lenses from Sony, Canon, Sigma, and more. Our custom optical grade acrylic domes provide the color, clarity, and durability of glass at a fraction of the travel weight.
Our new soft touch lobed zoom knob puts a unique system of universal zoom gears right at your fingertips. We provide two zoom sets with each housing, one for use with most popular larger diameter zoom lenses and a second designed for use with smaller diameter zoom lenses. Both sets are lightweight and easy to install with no modification to the lens required. A variety of dome and flat ports attach with four locking latches for maximum security and quick changes between dives.
A compact mounting tray attaches to the camera's tripod attachment point and slides into the front of the housing simply and securely.
Sony created a fantastic control set for this camera series, mimicked in the housing by larger controls and push buttons which are easy to access even with thick gloves. Control symbols laser engraved into the back of the housing will never peel off or fade even with years of use.
With a system of this caliber, a tray with handle is essential for the attachment of lighting and comfortable handling in a wide variety of shooting scenarios. This housing includes a balanced aluminum tray with our signature quick release handle for easy attachment and removal of strobes and video lights. This unique handle is curved slightly to fit the natural curvature of your hand, and features a soft over-mold which makes it a delight to hold. The complete tray and handle detaches quickly with the removal of two screws for travel. A new modular tray provides a 1/4-20 tripod mount and allows for the attachment of a second right-hand handle to the existing tray.
See the O-Ring Seal
An o-ring works best when it's true to its original form. 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. For added reassurance, there's no substitute for inspecting the actual o-ring seal through the back of your housing once it is closed. Polycarbonate is fundamentally corrosion-resistant for easy maintenance year after year.
This housing requires the addition of a compatible Lens Port for waterproof operation. Lens Port not included.
