Sea & Sea 30L DX Extension Ring

Sea & Sea 30L DX Extension Ring | SS-30144

The Sea & Sea 30L DX Extension Ring is precision-machined to bridge the gap between your housing and port. It’s a simple but critical link in the chain, one that directly impacts image quality and autofocus speed.

• Restores critical focus distance. Without the right extension, macro shots miss the mark entirely. This ring positions the port exactly where it needs to be for sharp, clear results.
• Built for demanding saltwater saltwater conditions. The marine-grade anodised aluminium construction resists saltwater corrosion, so you won’t find it seizing up after a season of use.
• Dry lock alignment system. A precise bayonet mount clicks into position with confidence, giving you a positive, leak-free seal before you even hit the water.
• Lens-specific compatibility. Designed for the Sea & Sea DX system, the 30L ring pairs naturally with standard macro ports, giving you that extra length needed for in-focus frames at close range.

Dive photographers who rely on the DX system know this piece isn’t optional?it’s essential. The 30L Extension Ring completes the setup, enabling tighter framing and sharper subjects without guesswork. Grab one and stop futzing with spacers.
