Marelux Aquista 135D Wide Angle Lens

The Marelux Aquista 135D (D meaning direct mount like the WACP line) is a direct-mount wide-angle optic built for serious underwater image-makers who want a bigger, cleaner view without the compromises of a traditional dome setup. With a 135° diagonal field of view and a rugged 100m depth rating, it’s designed for demanding dives and reliable results.

• Go wider in real dives: 135° (on full frame with a FF lens set at around 26-28mm) diagonal coverage helps you fit reefs, wrecks, big animals, and diver scenes without backing up.
• Direct-mount confidence: Series 5 “D” (direct mount) interface is built for secure, repeatable setups and fast changes between dives. 
• Built for saltwater abuse: Hard anodized aluminum alloy body with anti-corrosion coating on the dome exterior.
• Cleaner images, fewer distractions: Anti-reflection coatings on optical surfaces help reduce flare and veiling glare in bright water.
• Balanced handling underwater: Neutral buoyancy feel reduces wrist strain and makes long swim-throughs and video moves easier.
• Deep-rated durability: 100m depth rating for technical profiles and overhead environments (when your full system is rated appropriately).
• More lens options over time: Series 5 mount supports extensions and port adapters, opening flexibility as compatibility expands.

Marelux Aquista 135D Wide Angle Lens

Ultra-wide, direct-mount dry optics for ambitious underwater scenes

If you’re chasing dramatic perspective underwater—sweeping reef walls, big-animal encounters, wreck interiors, or diver portraits with strong foreground—coverage matters. The Aquista 135D is designed to deliver an expansive 135° diagonal view with a direct-mount Series 5 interface, built to stay solid on the boat, in surf entries, and at depth.

Why This Product Matters

Wide-angle underwater photography isn’t just about “fitting more in.” The right optic helps you get close (for color and contrast) while still capturing the full scene. The Aquista 135D is purpose-built for that real-world need: an ultra-wide view in a durable, dive-ready housing-friendly format, with coatings designed to stand up to saltwater and control reflections when the sun is high.

Real-World Performance

The Aquista 135D targets the kind of wide coverage you want when subjects are moving and distance is not your friend. On full-frame systems, it’s intended to achieve up to a 135° diagonal field of view with compatible lenses set around the 26–28mm range. Neutral buoyancy helps the system feel more predictable underwater—especially helpful for long swims, steady video shots, and fine composition work when you’re hovering close to the bottom.

Optical coatings play a practical role underwater. The dome exterior features anti-corrosion protection, while anti-reflection coatings on other surfaces help limit flare and unwanted reflections—particularly useful in shallow water, bright sand, and backlit scenes.

Creative Flexibility & Control

One of the biggest advantages of the 135D design is how it integrates into a modular port ecosystem. The Series 5 port mount is built to work with extensions and port adapters, giving you a path to tailor your setup to different camera and lens combinations as supported configurations expand. That means you can build a system that matches your shooting style—whether you prefer reef scenics, CFWA-style compositions, or dynamic swim-through sequences.

Who This Product Is For

• Wide-angle shooters who want maximum coverage: Ideal for big scenes, big animals, wrecks, and dramatic foreground storytelling.
• Divers who demand rugged gear: Hard anodized aluminum and 100m rating for challenging environments.
• Hybrid photo/video creators: Neutral buoyancy handling helps with smoother movement and steadier framing.
• System builders: Series 5 mount supports a modular approach with extensions/adapters.
• Traveling shooters who can’t afford surprises: Direct-mount architecture favors repeatable setup and dependable fit.
