AOI AX Port System for Sony Mirrorless Cameras – Dome Ports, Flat Ports & Extensions
The AOI AX Port System gives underwater photographers a flexible platform to build a setup that fits their gear and their goals. It’s built to work with Sony mirrorless systems and offers a modular way to support everything from close-up macro work to wide-angle coverage.
All components use the AX mount, connecting directly to AOI housings with consistent fit and reliable compatibility. Whether you're working with shorter macro lenses or wider glass, the system includes matching port types and extension rings to help you get the right alignment and performance.
It’s easy to expand over time. Start with what you need, then add ports or accessories as your setup evolves. You’ll really appreciate how well it all fits together—especially when you're prepping in tight quarters or switching configurations between dives.
Some Featured Choices:
- AOI DLP-102 Dome Port (220mm) – Larger dome for serious wide-angle work, especially useful when shooting expansive underwater scenes.
- AOI FLP-103 Flat Port (26mm) – Ultra-compact flat port that’s perfect for macro rigs or lightweight travel setups.
- AOI ER-AX_AX-60 Extension Ring – A versatile mid-length ring that works well for balancing longer lenses or dome adjustments.
- AOI LG-SEL-90-GMACRO Focus Gear – Made to fit the Sony FE 90mm macro lens; adds precise manual focus control underwater.
Essential Accessories for AOI Dome & Flat Ports
When using an AOI AX dome or flat port—or really any dome port—there are a few extras that can make a big difference and may even be essential depending on your setup:
- Zoom/Focus Gears
Lenses like the Sony 16–50mm or 90mm macro typically need a gear for manual zoom or focus control. - Extension Rings
Used to set the correct distance between lens and port. Without one, you risk vignetting or soft corners. - Port Caps
Easy to forget—until you scratch your dome. Caps protect your ports during storage and travel. - Anti-Reflection Rings
Help minimize internal reflections, especially with domes and wide-angle lenses. - O-Rings & Grease
Basic but vital. Always keep spare O-rings and silicone grease with you for your seal.
