Overview / Product Description
Ikelite 200DL Underwater Housing for Sony a7 IV Mirrorless Digital Cameras
A full-featured and durable waterproof housing for Sony Alpha IV full-frame mirrorless digital cameras. Suitable for scuba, snorkel, surf, pool, and any application in or around the water.
Sony Alpha 7 IV Mirrorless CameraNew in 2022, Sony's 4th generation affordable full-frame mirrorless camera continues to build on its reputation for high-quality image and video quality. A new 33-megapixel BSI-CMOS sensor provides image resolution up to 7008 x 4672.
The improved autofocus tracking system incorporates tracking Eye AF as well as some animal tracking in both still and video modes. Pattern detection, color, and brightness variations are also worked into its tracking AF algorithm providing a simple and effective experience.
Unlike its predecessor, the a7 IV is capable of shooting 4K/60p video which is great for underwater work where you want to slow things down in post-production. The increased frame rate does come at a cost of sensor usage, effectively cropping the resulting footage to APS-C dimensions.
Battery life is reduced a little to 580 shots per charge when using the rear LCD (CIPA). This is still a fair bit more than its competitors in the field: the Canon EOS R6 and Nikon Z6 II. All in all the Sony a7 IV is a great camera to shoot underwater with a wide variety of lens options from Sony, Sigma, and Canon (using a Metabones adapter).
Lens PortsThis housing features Ikelite's robust Dry Lock (DL) port system. "Dry Lock" refers to the placement of the o-ring on the outside of the port mount. This improves visibility and reduces the chances of water dropping onto your precious camera sensor. 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 large, soft-touch knob on the side of the housing makes fine-tuned adjustments a breeze. Zoom and focus gears differ depending on which lens you are using. Zoom gears are sold separately.
ConfidenceThe unique rear seal design prevents accidental twisting or stretching of the o-ring for simple and confident assembly. Ikelite has eliminated the need for an o-ring groove or channel which can trap sand, dirt, or debris. Three 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 TestingA 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 # 47011 allows you to draw a vacuum on the housing to check for leaks before 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.
M16 Accessory PortThe spare M16 threaded accessory port provides an attachment point for third-party accessories including HDMI bulkheads.
TTL ExposureThis housing 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.
Reliable locking connectors between the hotshoe and bulkhead make it easy to install the TTL hotshoe or carry backup parts when traveling to remote locations.
ErgonomicsGood ergonomics are critical when you need to concentrate on composition, focus, and proper exposure. Large, curved control levers put the most important controls right where you need them: shutter and autofocus (via the AF-ON button). This combination allows you to shoot with or without back button focus, an advanced technique that is useful for tack sharp focus of super macro and fast-moving subjects. Each lever can be extended using the optional Trigger Extension # 4077.95 for perfect spacing when using a right-hand handle.
The rotating controls are all operated intuitively via premium soft-touch knobs. An oversized, lobed knob puts the zoom/focus knob at your fingertips while your left-hand stays on the handle. Stainless steel, direct-drive rotating controls are virtually fail-safe and user-serviceable, and adjustable in a pinch.
All rear camera buttons are accessible by smooth action, hard-anodized aluminum push buttons for reliable performance and easy maintenance. These controls are clearly labeled by laser engraving on the back of the housing that never fades or falls off.
Set-UpThe 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.
ViewfindersThe 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 # 6890.2 or 45° Magnified Viewfinder (Type 1) # 6891.1.
Handling and TravelThe housing, tray, and handles have been optimized to reduce weight while maintaining strength and durability. The Right-Hand Quick Release Handle # 4077.02 (sold separately) can be added or removed depending on your needs. The precision-machined aluminum base features 1/4-20 tripod mounting sockets and additional mounting locations for future accessories. The base and handle can be quickly removed when breaking down your system for travel.
A 1/4-20 threaded mounting point is located front and center on the housing above the lens port mount. This mount can be used to attach lightweight accessories like a focus light or GoPro camera.
If you're shooting with two strobe or lighting arms, then a top handle can be added to carry to and from the dive site. Top handles are available in a Cable Grip # 4080.07 or Aluminum Top Handle # 4080.08. The rigid aluminum version provides additional mounting points for lighting and accessories.
Adding a dedicated focus light to your top mount or strobe arm is highly recommended for more accurate autofocus in low-light settings.
Durability and Corrosion-Free PerformanceIkelite's white ABS-PC blend housing provides strength and corrosion-free performance year with minimal maintenance. ABS-PC is lighter than aluminum for convenience during travel and less drag underwater. The specially formulated color deflects the sun to keep your camera running cooler, and longer. Compared to black or clear housings, the light color provides superior contrast for an enhanced view of the camera, LCD screen, and o-ring seal.
Made in the USAIkelite products are designed, built, and tested in the USA. Ikelite uses locally sourced, top-grade materials. Ikelite's housings are built by hand and individually tested for fit and function. Every unit is water pressure tested to 200 feet (60m). Ikelite backs their products with over 50 years of experience and the best reputation for service within the dive industry.
