Overview 

Dive into the hidden universe of miniature marine life with the WEEFINE WFL03, a premium underwater close-up lens designed for extreme macro photography. Engineered with precision optics, this powerful +12 diopter lens allows you to focus at an incredibly short distance of 3-6cm, transforming your standard setup into a powerful macro system that reveals textures, patterns, and behaviors invisible to the naked eye.

Key Features & Benefits:

• Powerful +12 Diopter for Extreme Close-Ups: With a true +12 diopter power (83.33mm focal length), the WFL03 enables stunning magnification, letting you fill the frame with tiny subjects like nudibranchs, pygmy seahorses, and coral polyps in breathtaking detail.
• Advanced Multi-Element Optical Design: Unlike simple single-element diopters, the WFL03 is constructed with 3 high-quality optical glass elements in 3 groups. This sophisticated design significantly reduces chromatic aberration and field curvature, delivering edge-to-edge sharpness and accurate color reproduction.
• Professional BBAR Coating & Anti-Reflection Treatment: All glass surfaces feature Multi-Layer Broadband Anti-Reflection (BBAR) Coating, ensuring less than 0.5% reflectivity across the visible light spectrum (420nm–680nm). Combined with matte-finished lens edges and spacers, this eliminates internal reflections, ghosting, and flare for perfectly clear images.
• Universal M67 Mount & Compact Design: Features a standard M67 x P0.75 thread for direct attachment to most underwater housing ports or via step-up/down rings. Weighing only 170g underwater, it maintains excellent buoyancy and handling without compromising on optical performance.
• Optimized for External Lighting: To achieve the best results, it is recommended to use natural light or external strobes/video lights. The lens itself may block the camera's built-in flash, ensuring you rely on professional, controlled lighting for perfect exposure.

Ideal for underwater macro enthusiasts and professional photographers, the WEEFINE WFL03 is an indispensable tool for exploring and documenting the fascinating microcosm of the ocean.
