Aquatica 20085 Sony A7r III & A7 III Housing with Vacuum Kit


Aquatica Sony A7r III & A7 III Housing with Vacuum Kit & either Nikonos, Ikelite, Optical or no Bulkheads

Aquatica, one of the pioneers in the underwater photo industry are proud to offer their underwater housing designed specifically for the Sony A7rIII 42MP full-frame mirrorless camera. The Sony A7rIII is sure to be a powerhouse for underwater digital imaging in both stills and video use.

About the Camera

The Sony A7rIII is currently Sony’s highest resolution, full-frame mirrorless interchangeable lens camera. The camera’s backbone is the 42MP BSI CMOS sensor offering a previously unheard-of frame rate of 10fps at 42MP and a buffer depth of 30 frames (in True 14 bit RAW) lets still shooters capture peak action with ease. The camera can capture 4K UHD video in both full-frame and Super 35 formats at up to 30fps. The Autofocus has been greatly improved over the A7rII, with the video AF less inclined to refocus to the background. Twin SD Card slots offer on-camera backups for all shoots. 5-axis image stabilization allows for smoother, more professional-looking video. A new FZ1000 battery now offers more than double the battery life compared to its predecessor, the A7RII.

The Housing

The Aquatica A7rIII housing is one of the smallest yet most ergonomic housings on the market. The housing’s design is centred on the user being able to concentrate more on the creation of their image rather than how to use the system. All the controls are set to be self-centering and are spring-loaded. The user only needs to set the camera on the tray and slide it into the housing, no alignment needed. Aquatica’s designers utilized a new method to access the new joystick (crucial for selecting any one of the 425 AF points on the sensor).

All of the buttons and dials on the housing are easily accessed without having to let go of the handles. Not that you’d want to as the grips are one of the most comfortable in the industry and they are included in the purchase price of your housing! Since the camera is easily user-customizable and the buttons mapped for almost any purpose, everything is literally at the user’s finger (or in this case, thumb) tips.

Of significant note, Back Button AF is fully supported with the housing. The AF-On control is easily reached by the user’s right thumb while the shutter release is simultaneously reached with the user’s forefinger. This lets the user continually track the subject in full autofocus and then fire the camera at the peak moment. Right below the AF-On button is the Video Record button. This placement is so the user will have no problems in accessing still or video capture. ISO values are easily changed as the camera natively has 3 dials set to change ISO values once the ISO button is pressed.

Surveyor monitoring system 

The Aquatica A7rIII housing comes standard with a Surveyor monitoring sensor. This sensor acts as a moisture and vacuum alarm for constantly monitoring the sealing integrity of the housing, adding another level of safety and peace of mind.


The Aquatica A7rIII is supplied with the Galileo type eyepiece. This high quality and coated optical finder gives a bright and full view of the viewfinder. For those seeking the ultimate in viewing for still image, the optional Aqua View Finder, available in straight and 45 degrees version, are among the best of the industry, they can easily be installed in a matter of a few minutes by the user. The enlarged and enhanced image provided by the Aqua View Finder is second to none in clarity, it provides the photographer with tack sharp corner to corner viewing of the camera viewfinder for composing and critical focusing.
