Acrylic vs Glass

Acrylic ports deliver solid image quality in most scenarios, and they have the advantages of being lighter, more affordable, and easier to repair. Glass dome ports, while offering slightly superior image quality in specific conditions and better scratch resistance, cannot be repaired if scratched.

6" vs 8"

The 6" domes deliver excellent image quality in most shooting conditions while being significantly more compact and travel-friendly, making them the preferred choice for many users. While 8" domes can offer slightly improved edge sharpness, their larger size makes them bulkier and less convenient to transport.

What is Surf Edition?

Dome Ports include a lens shade that protects them from accidental contact with objects during use and offers benefits in some shooting conditions. The Surf Edition Dome Ports are designed without a lens shade to minimize drag when shooting in large waves.
