Features
- Lens Ports - 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. Our new DL series ports are lighter and more adaptable than their FL counterparts. They accommodate popular large diameter, full-frame lenses with ease. The DL system is essential if you're considering shooting professional quality lenses like the Sony 28mm lens with Fisheye Conversion Lens or Canon 16-35mm f/2.8L III. 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. A large, soft-touch lobed 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. All are lightweight and affordable. Refer to the DL System Port Chart for Sony Alpha Series to choose the correct gear. Zoom gears sold separately.
- Using Legacy Four Lock (FL) Ports - Due to differences in mount diameter and zoom engagement, DL and FL system ports cannot be used interchangeably. The DL port mount may be removed and replaced with the Port Locks for FL Port System (Set of 4) # 5509.04 for legacy users with standard or modular ports from our Four Lock system. This modification will prevent the use of newer DL ports. The housing cannot be converted back and forth repeatedly. Re-installation of the DL port base will require the housing to be returned to Ikelite or an Authorized Dealer and will incur additional service charges. There are significant advantages to upgrading your lens ports which you can read about here. For example, if you're shooting an 8" diameter dome, you'll also save almost 2 pounds by using the DL version instead.
- 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.
- 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 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. See photos taken with the DL2 DS Link Sony TTL Converter... 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.
- Controls and Set-Up - The shutter and AF/MF/AEL button are set apart by ergonomic and sensitive curved lever actuators. Both controls can optionally be extended using the Shutter Trigger Extension # 4077.95 for more comfortable use when using a right-hand quick release handle. If you're not already using back button focus, we recommend learning this valuable trick. All knob controls are upgraded to our new soft-touch design which gives you extra grip and feels good whether you're diving with gloves or bare hands. Our push buttons have been redesigned to reduce weight and salt build-up. The back of the housing features laser engraved control symbols which will never fade or fall off. Control placement mimics the way you use the camera on the surface to take advantage of muscle memory and avoid the need to re-learn your camera's controls. 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.
- 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.
- Viewfinders - The included SuperEye Viewfinder provides an enhanced view of the camera's optical viewfinder when viewed through a dive mask. The viewfinder removes quickly and easily for the attachment of an optional Straight Magnified Viewfinder # 6890 or 45° Magnified Viewfinder (Type 1) # 6891.1.
- Handling & Travel - Overall the housing is over 1/2 pound lighter than a typical FL counterpart. Our new hard anodized aluminum base with quick release handle has also been streamlined for travel and is over 3/4 pound lighter than our previous DSLR tray and handle system. The Right-Hand Quick Release Handle # 4077.02 (sold separately) can be added or removed depending on how you want to shoot. The precision machined aluminum base features 1/4-20 tripod mounting sockets and additional mounting locations for future accessories. Plus, 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 make the system easier 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.
- Construction - Our 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).
- 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. 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.
- 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.
- Fiber Optic - Fiber optic only strobes are not compatible with this installation. An external strobe must be connected by electrical sync cord.
- Remote Triggering - 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 product # 4405 or the Water Wizard system (manufactured and sold by Aquatica).
- Compatibility - This housing is only compatible with the Sony Alpha A7 II, A7R II, and A7S II cameras as shipped by the manufacturer. Unless otherwise noted, this housing does not accommodate the use of add-on grips, battery grips, eyepieces, LCD covers, or other accessories. Differences in lens and control placement prevent other camera models from being used in this housing. This housing is not usable A7 (Mark I) or Mark III cameras. We are not aware of any other models which may be used in or adapted to this particular housing.
