When shooting for true close-up with an interchangeable lens camera, a ring flash with an emitter around the lens is used to avoid casting shadows on the subject. The similar effect can be achieved with the LED Light Guide. The LED Light Guide, LG-1 can be attached to the lens of the TG-3, using the built-in LED light to evenly illuminate the subject, drawing out the best of the TG-3's macro photography abilities. The LG-1 is compatible with the TG-1, TG-2 and TG-3. The perfect accessory for internet sellers or anyone who wants to take excellent pictures of small indoor objects. NOTE: Although this item can be left on the camera when underwater, the item is not recommended for actual usage as a lighting accessory. The underwater results would not be desirable.
