Diveavenue's expert opinion MARELUX MX-A7R IV Waterproof Housing

We tested this housing for you in real-world conditions, and the 125 mm port diameter really makes a difference. Being able to slip the housing on with a 16–35 mm lens already attached, without having to fiddle with the optics on the boat, greatly reduces the risk of dust getting in. The contrasting green seals allow for a quick visual check at a glance, providing welcome peace of mind during the rush of preparations between dives.

Frequently Asked Questions (FAQ)

Can bulky lenses be used? Yes, the record-breaking internal diameter of 125 mm accommodates most wide-angle and macro lenses used with the Sony A7R IV without any difficulty.

Do you need to buy the vacuum system separately? ? No, the vacuum leak-testing system is included as standard; you may only need the hand pump if you don’t already have one.

Is the subwoofer compatible with other Sony models? This model is specifically designed for the Sony A7R IV; we do not recommend using it with any other Sony Alpha camera body to ensure full functionality.
