Focus Knob for 22170

This is a replacement focus knob designed for use with housings that accept the 22170 zoom gear. It provides direct, tactile control over your lens focus, essential for critical underwater macro and portrait work.

The knurled cap offers a positive grip, even with thick gloves. It secures firmly to the gear shaft, preventing slippage during adjustments. This knob maintains the operational feel expected from a Nauticam control, ensuring consistent performance. Check the compatibility finder for specific housing and lens combinations that use the 22170 gear.

Regular maintenance of all control surfaces, including focus and zoom knobs, helps prevent wear and ensures smooth operation. You can find essential spare parts and maintenance guides on our support pages.
