Create soft, beautiful lighting for close-up and macro photography by attaching the Olympus FD-1 Flash Diffuser to your Stylus TOUGH TG-1, TG-2, TG-3, or TG-4 Digital Camera. It mounts to the front of your camera where it channels and diffuses light from the built-in flash. The light is projected in a ring around the lens, a common trick for close-up imaging, at distances from 0.8 to 11.8". There is also a light intensity adjustment lever with high or low output settings, with a 1.4-stop difference between them, in order to work with a range of subject matter. Additionally, when using a TG-4 with firmware version 2.0, users will have access to additional settings and features.
