Marelux

Precision housings, one camera at a time

Marelux makes underwater housings and the parts that go around them, and that is essentially all it makes. Every housing here is CNC-machined from hard-anodised aluminium and built around a single camera body, so the buttons, levers and dials sit under your fingers where the camera's own controls would be. That matters when you are wearing gloves and the shot is swimming away. It is precise, premium kit, bought by photographers who already know what they shoot.

The housings we stock

Eight housings, each matched to one body. There is no universal shell in this range — you buy for the camera you already own.

Sony

The Sony line is the deepest. The MX-A1 houses the Alpha 1, the MX-A7IV takes the A7IV, and the MX-A7RIII and MX-A7RIV cover the A7RIII and A7RIV. The MX-FX3 is the one to look at if you shoot video rather than stills: it is built for the FX3 cinema camera, and its listing notes multiple accessory mounts for lights, arms and monitors, plus optional HDMI bulkheads if you want an external monitor on the rig.

Canon and Nikon

For Canon, the MX-R5 takes the R5 and the MX-R6 takes the R6 — similar cameras, separate housings, so confirm which body you have before ordering. For Nikon, the MX-Z6II/Z7II is the exception that covers two bodies, fitting both the Z6II and the Z7II. Construction and control layout follow the same approach as the Sony housings.

Ports, gears and the rest of the rig

A housing on its own will not take a photograph. The port is the window your lens looks through and it has to suit that specific lens; if the lens needs focusing or zooming once you are in the water, it needs a gear as well so the housing's control can turn it. We stock the Marelux Macro port 32 and the Marelux Focus Gear for the Sony FE 90mm F2.8 Macro G OSS, which together make the classic macro pairing on a Sony body.

The Marelux 45 Degree Viewfinder is a patented design and it changes how you work close to the bottom: you look down into the finder rather than straight through it, so you can shoot upwards at a subject on the sand without flattening yourself into it. The Manual Flash Trigger sits inside the housing and fires your strobes — the MX-A7RIII listing specifies dual fibre-optic flash ports for that connection.

Buying into the system

Sealing and pre-dive confidence

Our listings for the MX-A7RIII and the MX-FX3 both note an optional vacuum and leak detection system. It is not in the box, but it is the first thing most owners add: you draw the housing down before the dive and watch for a steady signal, so a bad o-ring shows itself on the boat instead of at depth. Both of those listings also give a depth rating of 100 metres. Read the individual listing for the model you want, because the figure is stated per housing rather than across the range.

Talk to us before you order

The parts of a Marelux rig have to agree with each other, and the cost of getting it wrong is a port you have to send back. Our team shoots underwater and we will happily map out a full build with you: body, housing, port, gear, viewfinder, trigger and lighting. Tell us what you dive and what you want to photograph, and we will tell you what you actually need — including when you do not need the extra part.
