Dive Deep with Zoom Gear
Sea Frogs Focus Gear for Sigma 20mm F1.4 DG DN Art E-Mount Lens
The Focus Gear for Sigma 20mm F1.4 DG DN Art E-Mount Lens allows access to manual zoom function in underwater housings. It mounts onto the lens’s zoom ring and controls it via the housing’s zoom dial.
Fits Sea Frogs housings with 90 mount.
Compatible with most Sea Frogs dome and flat ports (excluding A6xxx and RX1xx housings).
How It Works:
- Engages the Lens Focus Ring – The focus gear, a ridged or toothed ring, attaches to the lens focus ring.
- Interfaces with Housing Controls – The housing has an external dial that meshes with the focus gear.
- Allows Manual Focus Adjustments– By turning the external control, the diver can manually adjust the lens focus.
Why It’s Important:
- Allows fine-tuned focus adjustments in low-light or high-turbidity conditions.
- Useful for video shooters who need precise focus control.
