Olympus FD-1 Waterproof Flash Diffuser for TG-4 & TG-5 Cameras

Improved light distribution darkens the background to make subjects stand out. Light intensity adjustment lever allows users to select either high or low output (a 1.4 step increment) to accommodate a variety of subjects. Illumination distance: 2 to 30cm. Ships with instruction manual. *Compatible with TG-4/5. TG-4 firmware Version 2.0 supports the FD-1. Although FD-1 may be attached to TG-1/2/3, some features are not fully supported.
