By Ian Bongso-Seldrup, July 20, 2026 @ 08:00 AM (EST)

Marelux is now shipping its underwater housing for the new Sony a7R Mark VI. The sixth iteration of Sony’s high-resolution full-frame mirrorless camera features a fully stacked 66.8-megapixel sensor coupled with the latest Bionz XR2 processor, delivering blackout-free 30fps continuous shooting (electronic shutter), 8K/30p recording (with a 1.2x crop), and oversampled 4K/60p full-width video.

Marelux’s housing is made from anodized aluminum alloy and features dual locking levers to ensure the housing is securely closed. A quick-release baseplate allows the camera to be inserted and removed easily. Ergonomically arranged around the built-in handles, controls for all the important camera functions are at your fingertips, including the all-important AF-ON button and the handy Q Menu button. Shipping with a vacuum detection and moisture alarm system, the housing is compatible with Marelux’s manual fiber-optic flash trigger.

Retailing for $3,398, the MX-A7RVI housing can be ordered directly from the Marelux website in various finishes—Black, Silver Gray, Yale Blue, Olive Green, and Burgundy.
