Weefine 230MM Optical Fisheye Glass Dome Port

The Weefine WDP230 is a true optical-glass dome port built for fisheye and wide-angle work when you want cleaner corners, better contrast, and more reliable over/under waterlines. With BBAR-coated glass and 95%+ light transmission, it’s designed to keep images crisp even in dim, flare-prone conditions.

• Sharper wide-angle results: 230mm glass dome helps keep edge detail and contrast where smaller domes struggle.
• Cleaner split shots: Large radius supports a thinner, steadier waterline for over/under images in chop.
• Brighter frames underwater: Precision coatings boost usable light (95%+ transmission) for truer exposure and color.
• Better flare control: Anti-glare/ghosting behavior helps when shooting toward sunbeams or powerful video lights.
• Built for real diving: Anodized aluminum construction with a 100m/330ft depth rating.
• Flexible mounting: Designed to work with Nauticam, Sea&Sea, and Marelux 120mm port systems via included adapters.
• Travel-ready protection: Supplied with protective storage and essential spares to keep you shooting.

Weefine 230MM Optical Fisheye Glass Dome Port

A precision glass dome port for wide-angle scenes, split-levels, and cleaner corner detail

If you shoot reefs, wrecks, big animals, or dramatic close-focus wide angle, the dome port is the piece that decides whether your frame looks crisp or compromised. The Weefine WDP230 is built around a 230mm optical-glass element with multi-layer BBAR coating, designed to reduce reflections, preserve contrast, and keep light working for you underwater—especially when the scene is dark, backlit, or full of particulate.

Why This Product Matters

Wide-angle underwater images are unforgiving: you’re often shooting into bright highlights, juggling strobes or video lights, and asking the lens to stay sharp from center to corner through a curved water-to-glass interface. A properly designed glass dome port can reduce flare, maintain contrast, and help your lens perform more consistently—particularly when you’re trying to capture the full scene without mushy corners or washed-out highlights.

The WDP230 combines a large 230mm dome with optical glass and anti-reflective coatings to support cleaner, more predictable results in the real conditions divers actually face.

Real-World Performance

• Split-level (over/under) shooting: The 230mm diameter makes it easier to hold a thin waterline, helping you keep both halves of the frame usable in light chop.
• Close-focus wide angle: A larger dome can be more forgiving when you push close to foreground subjects while keeping the background expansive.
• Backlight and video-light scenes: The coatings are designed to suppress stray reflections and ghosting, which can be the difference between a punchy image and a hazy one.
• Low-light reefs and dusk dives: With 95%+ light transmission, you keep more brightness and detail instead of losing it to surface reflections.

Creative Flexibility & Control

The WDP230 is made for photographers and videographers who want more control over how wide-angle images render underwater. Glass typically handles flare better than acrylic, and the WDP230’s coated element is built to reduce glare and internal reflections when bright highlights enter the frame. That matters when you’re shooting sunbursts, silhouettes, or strong beams from video lights.

Compatibility is also part of control: this dome is designed to integrate into popular 120mm port ecosystems (Nauticam, Sea&Sea, Marelux) via adapters, letting you build a system around the lenses you actually use.

Who This Product Is For

• Wide-angle and fisheye shooters who want a true glass dome port for higher contrast and a more premium optical surface.
• Split-shot (over/under) creators who benefit from a large dome diameter for a steadier waterline.
• Traveling divers who want a complete kit with protective storage and essential spares included.
• System builders using Nauticam, Sea&Sea, or Marelux 120mm port systems and looking for a compatible 230mm glass option. Adapters for all 3 brands included.

Ready to Shoot With Confidence

If you’re investing in wide-angle underwater images—split-shots, dramatic reef scenes, wreck interiors, big animals—the dome port is not the place to compromise. The Weefine WDP230 gives you a coated glass optical surface, a true 230mm diameter for more forgiving wide-angle rendering, and a dive-ready build rated to 100m. Pair it with the correct port configuration for your lens, and you’ll get a setup that’s easier to trust when the moment happens once.
