The A70D Underwater Housing from Aquatica is a waterproof case enabling you to shoot beneath the surface with your Canon EOS 70D DSLR Camera. It has a depth rating of 295', which is upgradeable to 426'. Mechanical controls provide easy access to virtually all camera functions, and dual ergonomic hand grips afford optimal handling and comfort. For convenience, vital functions can be accessed while keeping your hands on the grips.
The housing is made of aluminum and stainless steel alloys. Anodizing the aluminum to military specifications ensures superior corrosion resistance. The A70D ships without a required lens port, though various interchangeable ports are available for wide-angle, macro and zoom lenses. For full compatibility, see Port Chart. The housing has one optical and one Nikonos connector for the attachment of optional external strobes via fiber-optic cables and sync cords. The standard, coated eyepiece offers a full view of the camera's viewfinder.
Features a depth rating of 295', which is upgradeable by request to 426'. The closure system is equipped with safety locks, and all control shafts are double O-ring sealed while all push-buttons have quad-ring seals. Aquatica has developed an atmospheric pressure sensitive circuitry that will allow you to confirm that the housing is watertight before the dive. Once your camera is installed, simply push the start actuation button. The LED light will turn green for 2 sec to confirm actuation. Once a solid vacuum is achieved, the LED will blink green again for 2 sec. During the dive, the LED will flash green every few sec, indicating system integrity. If the vacuum starts to decrease, the LED will start to flash orange. If water is detected, the audible alarm, which is always activated and ready to go, will go off and the LED will also flash red. The advanced circuit compensates for changes in ambient and internal temperature to prevent incorrect readings.
Controls and Handling
Mechanical controls provide easy access to virtually all camera functions, and dual ergonomic hand grips afford optimal handling and comfort. For convenience, vital functions can be accessed while keeping your hands on the grips. The controls are knurled for a better grip, and oversized and spaced out well enough to allow for easy access and precision, even while wearing thick gloves. Access to the Quick Command knob has been redesigned from previous housings, and is now positioned at a comfortable angle, right next to the main command knob. The AF-ON /* lever is fitted with a rotating collar allowing access without the need for obstructive levers. ISO functionality is now possible with a thumb-activated lever, and you can also flip the internal flash up and down. Additionally, access to video functions has been made easier than it was on previous housings, allowing for smoother operation and transitions.
Body and knobs crafted from 6061 T6 aluminum, which is anodized to MIL-A-8625, type 2, Class 2 specification, then treated with a certified A.A.M.A. (American Architectural Manufacturers Assn.) 2603-98 polyester powder coating and baked at 350.6° F / 177° C. The push-button controls are constructed from Type 304 stainless steel. Housing fits the Canon 70D like a glove, and allows for quick and easy camera insertion via the camera tray. The housing has been tested under the ice of the Arctic Polar cap and withstood months of harsh winter conditions in Antarctica. Dual sacrificial anodes mounted on the front and rear of the housing protect key components by corroding instead of said components.
The A70D ships without a required lens port, though various interchangeable ports are available for wide-angle, macro and zoom lenses. There are 4 hemispherical dome ports: the 4" mini dome, the 6" dome, the 8" dome and the 9.25" Megadome. Three flat ports are available, as well. Nine port extension rings expand your possibilities further. For full compatibility details, see the Port Chart linked above. A port lock mechanism safely secures the port to the housing.
External Strobe and Light Use
The housing has one optical and one Nikonos connector for the attachment of optional external strobes via fiber-optic cables and sync cords. Also provided are adapters for Inon type and Sea & Sea type optical sync cords. Manual exposure control is available, and the housing is ready to accept a third party TTL converter, which is available separately and will enable TTL flash exposure for strobes attached to the Nikonos connector. This connector is switchable from 6 pins for use with a TTL converter to 2 pins for full manual strobe exposure. Strobes attached to the optical connector can benefit from S-TTL exposure without a converter. Aquatica's strobe connectors are user-serviceable and quickly replaceable, without any special tools.
Viewfinder and LCD Use
Standard, supplied Galileo type eyepiece is a coated optical viewfinder offering a full view of the camera's viewfinder.
Strobes and video lights can be connected to optional support arms, such as Aquatica's Technical Lighting Control arms, which can be conveniently mounted on the housing's grip handles. Five ¼"-20 threaded holes are available on the top and three more are on the bottom. Extra 16mm and ½" pass-through bulkheads enable connection of optional accessories, such as video monitors or a hydrophone for the recording of sound.
Vacuum Check System
This version of the housing also includes a vacuum check system pre-installed at the factory. This system consists of a vacuum valve and extracting pump.
