Nauticam Mirrorless Extension Rings for N85 & N100 Ports

Nauticam extension rings make it easy to get the right distance between your lens and port when using mirrorless underwater housings. They’re a simple but vital part of getting your setup to work as it should—especially when you're fine-tuning for optical performance.

These port extension rings are constructed from anodized aluminum, and depth-rated to 100m, the rings come in different lengths from 20mm to 50mm. Whether you’re using an N85 or N100 port system, there are options like the Mini Extension Ring 20 and Nauticam N100 Extension Ring 50 II that slot seamlessly into your Nauticam rig.

The right extension ring helps ensure your lens lines up properly inside the housing. That means sharper corners, better focus accuracy, and full control of zoom or focus gears—without trial and error on your dive trip.

Extension rings are typically used alongside a matching dome port or flat port. To make sure everything lines up, we always recommend checking the official Nauticam port chart for your specific lens.
