Overview

The Weefine WFL17 is a premium underwater conversion lens engineered to revolutionize your underwater photography. It seamlessly converts a standard 23mm (35mm equivalent) lens into an immersive, ultra-wide 150-degree optical system, allowing you to capture expansive seascapes, large marine life, and complex scenes with stunning clarity and minimal distortion.

Key Features & Benefits:

• Extreme 150° Underwater Field of View: Go beyond the limitations of your standard lens. The WFL17 unlocks a massive 150-degree diagonal angle of view, letting you capture the vastness and grandeur of the underwater world in a single, breathtaking frame.
• Advanced Optical Glass Construction: Designed with a sophisticated formula of four high-quality optical glass elements, the WFL17 utilizes high-refractive-index and low-dispersion materials to meticulously correct chromatic aberration, distortion, and other optical imperfections, ensuring sharp, color-accurate results.
• Extended Hyperfocal Distance for Close-Focus Wide-Angle Shots: A unique optical benefit that allows you to focus on very close subjects while maintaining a sharp, wide-view background. Perfect for capturing detailed foreground subjects like a sea anemone with the entire reef scene behind it in clear focus.
• Integrated Lens Hood & Robust Build: Features a custom-designed lens hood that serves a dual purpose: it effectively minimizes lens flare from stray light and provides the best physical protection for the dome. The lens barrel features a standard M67 x P0.75 thread for secure mounting to most underwater housings.
• Professional-Grade Design Principles: The WFL17 is engineered with water as a key optical element in the system. For optimal performance, the space between the lens and the housing port must be water-coupled to eliminate air bubbles that can disrupt image quality.

Technical Highlights:

• Conversion: Transforms a 23mm (35mm Equivalent) lens to a 150° FOV system.
• Construction: 4 high-quality optical glass elements + 1 hard-coated polycarbonate dome.
• Key Feature: Extended hyperfocal distance for close-focus wide-angle shots.
• Mount: M67 x P0.75 thread.
• Included: Custom-built lens hood with set screws.

Recommended Use:
For the best results, use the WFL17 with natural light or external strobes/video lights, as the built-in camera flash will likely be blocked by the lens. Position external strobes carefully to avoid creating ghost images by pointing them directly at the lens.

Ideal for advanced amateur and professional underwater photographers, the WEEFINE WFL17 is an essential tool for anyone serious about capturing the true scale and beauty of the marine environment.
