Dome Ports vs. Flat Ports for Underwater Photography: Advantages, Differences, and When to Use Each
Dome ports deliver better optical results than flat ports for underwater and split-level photography. Key reasons: domes correct light refraction and magnification underwater, larger domes outperform smaller ones, optical glass is superior to acrylic, and the universal fit of Outex domes protects your investment across any lens. Flat ports remain the better choice for above-water use due to their lighter weight and nano-coated hydrophobic surface.

Why Optical Glass Domes Outperform Flat Ports Underwater
Dome ports outperform flat ports underwater by correcting refraction, restoring the lens's natural field of view, reducing edge distortion, and enabling clean split-level photography. Optical glass domes further outperform acrylic domes on sharpness, scratch resistance, anti-reflective properties, and long-term durability. This article explains both comparisons with real photo examples.

Dome Ports vs. Flat Ports: What the Results Actually Look Like
Real photo examples showing the difference between Outex dome ports and flat ports for underwater and split-level photography. Dome ports correct refraction and magnification underwater, delivering sharper, more color-accurate images — especially for split-level (half above, half below water) shots. Flat ports are lighter and better suited for above-water use.

Outex Dome Ports: 120mm vs. 180mm — Which Should You Choose?
Outex makes two optical glass dome ports: the Dome 120mm and the Dome 180mm. Both work with any lens via adaptors (threaded lenses) or clamps (unthreaded, fisheye, hooded lenses). The 180mm delivers better results in more conditions — especially for split-level photography — while the 120mm offers better portability and value. Both are fully compatible with all Outex covers and accessories.
