Weefine WFL14 150° Ultra-Wide Underwater Conversion Lens

Weefine WFL14 - 150° Ultra-Wide Underwater Conversion Lens

Ultra-wide underwater photography with up to 150° field of view

The Weefine WFL14 is a high-quality underwater wide-angle conversion lens designed for action cameras with a 1-inch sensor and an ultra-wide field of view.

With a maximum 150° underwater field of view, the WFL14 allows you to capture expansive underwater landscapes, large marine animals, wrecks and dynamic close-focus wide-angle compositions.

The lens is designed to restore an exceptionally wide field of view underwater, where a camera's standard optics would otherwise lose coverage due to refraction.

Fits especially: WFH-GP1 Action Camera Dive Housing.

Optical construction

The WFL14 uses an optical design with four elements in four groups, including three optical glass elements and a hard-coated polycarbonate dome.

A combination of high-refractive-index and low-dispersion optical elements helps minimise unwanted optical aberrations and maintain image quality.

All glass elements feature Broadband Anti-Reflection (BBAR) multi-layer coatings, providing less than 0.5% reflectivity per surface across the visible spectrum of 420-680 nm.

The outer dome is manufactured from optical-grade polycarbonate with a hard protective coating.

Aluminium construction

The lens barrel is manufactured from aluminium alloy with Type II anodising, providing durability and corrosion resistance for demanding underwater environments.

Rated to 80 metres, the WFL14 is suitable for recreational and technical diving applications.

M67 mounting

The WFL14 features a standard M67 x 0.75 threaded mount, allowing direct attachment to compatible underwater housings with a matching female thread.

The WFL14 is shown paired with the Weefine WFH-GP1 underwater housing, which is sold separately.
