The Olympus LG-1 LED Macro Ring Light is specifically engineered for compatibility with the Tough TG-6, TG-5, TG-4, TG-3, TG-2, and TG-1 digital cameras. This device can be easily attached and detached while submerged in water, effectively transforming the camera's LED illuminator into a uniform, circular light source that is ideal for close-up and macro photography.
