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

We tested the MX-A7R IV for you during dives where visibility was variable. What really stands out is how easily the camera fits into the housing thanks to the large port diameter, even with a lens already attached. The green seals are a real game-changer when it comes to maintenance: you can spot even the tiniest speck of sand immediately before closing the housing. It’s a rigid and precise chassis that feels reassuring from the moment you pick it up, especially when handling a camera body of the calibre of the A7R IV.

Frequently Asked Questions (FAQ)

Can bulky lenses be used with this housing ? Yes, the 125 mm mount diameter is currently the widest on the market, allowing you to fit large lenses without having to remove the lens from the camera body.

Is the vacuum system compulsory for every dive ? It is strongly recommended that you use it, as it allows you to check that the housing is properly watertight before descending, thereby preventing any risk of accidental drowning.
