Usage Tips:The MRL-TG1 light guide ring is designed for Tough series cameras -7, -6, -5, -4, -3, -2, and -1. It directs the camera's LED lighting into a circular, uniform light source, making it ideal for close-up and macro photography. When using an interchangeable lens camera for close-up shots, a circular flash with an emitter around the lens helps avoid casting shadows on the subject. LED light guides can achieve similar results. The LED light guide plate attaches to the lens of compatible series cameras, using the built-in LED to evenly illuminate the subject and enhance macro photography performance. It can be attached and removed underwater. Compatible with TOUGH cameras: -5, -4, -3, -2, -1 (Series) 1: Replaces -1 Light Guide – Specially designed for -7, -6, -5, -4, -3, -2, and -1 cameras. 2: Easy to Install – The light guide ring rotates and mounts directly onto the camera lens, utilizing the built-in LED as a light source to evenly illuminate the subject. 3: Enhanced Lighting for Macro – Channels the camera’s built-in LED for improved, even lighting during macro photography.
