Zoom Gear: Unseen Beauty

Sea Frogs Zoom Gear for Sigma 18-50mm F2.8 DC DN E-Mount Lens

For Housings with 90mm Bayonet | Polycarbonate

Also available on the European website

The Zoom Gear for Sigma 18-50mm F2.8 DC DN 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 - The zoom gear, typically a ridged or toothed ring, wraps around the zoom ring of the lens.
Interfaces with Housing Controls - The housing has a mechanical control (dial wheel) that meshes with the zoom gear.
Allows Zooming - By turning the external housing control, the gear rotates the lens's zoom ring, adjusting the focal length.

Why It's Important:

Enables framing flexibility without opening the housing.
Works with Dome and Flat ports.
Essential for video shooters and photographers using zoom lenses.
