Isotta Sony A7R III & A7 III Underwater Housing

Compatible with Sony A7R III & A7 III Cameras

The Ferrari of the Sea


"My initial thoughts after having a chance to handle the housing myself is that Isotta is well made and ergonomic. The back door is easy to open and close, port lock system is very reliable, the controls are easy to access, the housings themselves are light weight and compact design. All ports include caps and the dome ports include neoprene port covers. Isotta offers housings for a wide range camera models and I think this brand will be a great addition to our product line." 
-Tommy Stylski, Bluewater Photo Staff 

Isotta has been known to produce high quality aluminum housings and their Isotta Sony A7R III Underwater Housing is certainly no exception. The underwater housing is small & compact in size, has excellent ergonomics and is very durable. It features a unique way to open the housing with its single-hand locking system. In addition, it uses a double o-ring seal design to ensure the integrity of the housings seal.

The Isotta A7R III housing has easy access to all key/main camera controls, even with gloves on, by means of the clearly labeled lasered long-life buttons. The back door of the housing has a large glass window, allowing you to easily view the LCD screen while shooting, as well as a viewfinder display depending on your desired shooting technique. The back door is fully removable from the housing to allow the camera to fit more easily inside the housing.

The housing offers two fiber optic connections to allow for the use of external strobes through the manual trigger. There are also three M16 bulkhead holes to accommodate peripheral attachments such as sync cords, vacuum valves and monitors. 

Isotta A7R III Housing Features:

One Hand Open/Close 

The housings can be easily be opened and closed using Isotta's innovative single-hand locking system. The single latch closing mechanism makes it unique and very effortless to operate yet secure with its double steel pins design at the bottom of the housing.


Double O-Ring Seal

The Isotta Sony A7R III Underwater Housing utilizes the double o-ring seal design to ensure that the camera is always safe and dry inside the camera. It is always good to have a redundant o-ring on your seal to make sure that everything will be a-ok while underwater.


Comfortable Handles

A pair of comfortable and ergonomically designed handles is included with the housing. Various accessories are available that can be directly fitted on the handles to make your shooting experience great.


Ergonomic Button & Lever Placement

The location of the button and levers has been well planned and everything is readily available at your fingertips. It makes operation of the camera very smooth. In addition to that, buttons have been laser-engraved so that it would be visible even in dark conditions.


Other Features:

  • Back Window - The back of the housing has a large glass window to display cameras LCD clearly.
  • Camera Installation - It comes with a camera tray with locking mechanism which makes installation very straight-forward and secures the camera in place inside the housing
  • Construction - Isotta housings is made from high quality thermo-coated & anticordal aluminum, which makes maintenance very simple.
