Weefine WFL09S (Underwater Ultra Wide Angle Conversion Lens)

The Weefine WFL09S is an underwater ultra-wide angle conversion lens designed to expand the capabilities of cameras equipped with a 60 mm (35 mm equivalent) lens. When mounted on compatible underwater housings with M67 × P0.75 threads, it broadens the field of view to a dramatic 154.8°, allowing you to capture expansive seascapes, large marine life and immersive underwater scenes with fewer shots.

Built with a precision 7-element, 6-group optical structure, the WFL09S combines multiple high-quality glass elements with a hard-coated polycarbonate dome to minimize optical aberrations and maintain sharpness across the ultra-wide field. Each glass surface features Broadband Anti-Reflection (BBAR) coating to reduce flare and ghosting, improving image contrast and clarity even in challenging underwater lighting.

This lens is versatile enough to work with both DSLR housings and compact housings that have a long lens port, offering photographers flexibility without sacrificing the ultra-wide angle effect underwater. Its robust construction and depth rating of 60 m makes it suitable for a wide range of recreational and professional dives.
