Diveavenue's expert opinion for MARELUX MX-Mini LF Waterproof Enclosure

The MX-Mini LF is the tool we choose for demanding underwater film projects. What I appreciate is the peace of mind provided by the pull-type vacuum valve: there’s no risk of accidentally breaking the vacuum whilst handling the housing on the boat. The fluorescent green seals are a game-changer during quick set-ups between dives, as even the tiniest grain of sand becomes immediately visible. It’s a technical housing, balanced underwater, which allows you to harness the image quality of the ARRI Alexa Mini LF without compromising on ergonomics.

Frequently Asked Questions (FAQ)

Can large-aperture lenses be used with this camera body ?

Exactly: thanks to the 125 mm diameter entry port, you can fit your bulky cinema lenses straight in, avoiding any complicated or risky fiddling around just before you get into the water.

How does the vacuum security alarm work ?

The system creates a vacuum inside the housing using the supplied pump. The built-in LED turns green to confirm that the seal is intact before submersion, then turns red and emits an audible alarm if the pressure changes or if moisture is detected.

Is the housing heavy to handle whilst diving ?

Although robust thanks to its aluminium construction, the overall volume is designed to provide the most neutral buoyancy possible, thereby reducing diver fatigue during long shoots.
