Nauticam Sony A7R III Underwater Housing

Also compatible with Sony A7 III camera

*Discontinued

The Nauticam A7r III underwater housing sets a standard of excellence for underwater housings. Nauticam has always been known to produce top quality aluminum underwater housings and is designed to have great ergonomics. This housing is smaller than a standard dSLR housing, has an excellent port lock system, and supports a huge variety of lenses. The bulkheads support different combinations of sync cords, external monitors and/or their highly recommended vacuum valve system.

Most people who use strobes with this housing end up getting the flash trigger, for faster firing through fiber optic cables. If you are shooting video, I'd recommend two underwater video lights. Almost everyone end up getting the optional vacuum valve. Last, but not least, keep in mind that ports are optional - you'll need at least one flat port or one dome port, depending on which lens you want to use.

Nauticam A7r III Underwater Housing Key Features:

Patented Port Locking Lever

The locking lever has become a signature of the Nauticam brand. No twisting or threading action is required to mount a port, and it locks securely in place with this lever. 

Integrated Vacuum Monitoring and Leak Detection

Provides constant monitoring of water tight integrity when combined with an optional Nauticam M14 Vacuum Valve II.

Front Vacuum Reset Button

A front reset button located in front of the housing has been placed to easily reset the vacuum and would not need to open the back of the housing.

Housing Locking Latches

Easy to use housing closure system, requiring very little hand strength to operate, secures the housing back in place. The latches are safely locked to prevent accidental opening, but are easy to open when needed for a quick battery or memory card change.

Mission Controls

Nauticam is known to provide great orgonomics.  Button placement has been well thought off, and make it easy to operate and navigate.

Ergonomic Rubberized Handles with Stainless Steel Support Brackets

Rubberized handles and oversized controls are easy to operate even when wearing thick cold water gloves. Handle support brackets are included with the housing, providing a solid "wobble free" attachment base to shoot from, even with heavy lighting systems.

Tripod Mounting Balls

Mounting points for three industry standard 1" mounting balls are machined directly into the bottom of to the housing, eliminating the need for accessory brackets to attach tripod legs.

Changes Made on the New Version:

• Decreased the number of dials from 3 to 2
• Increased the size of the dials for easy operation even with gloves.
• Added an additional M16 bulkhead port which videographers would benefit for adding a monitor to their rig.
