Included with numerous PEN-series mirrorless Micro Four Thirds cameras, the Olympus FL-LM1 Flash, offered here as a replacement or spare, allows users to add a little bit of fill light to their scene or trigger slave flash units remotely from the camera body. It has a guide number of 23' at ISO 100 and has a wide coverage of 14mm lenses in the Micro Four Thirds format. Also, the flash is compatible with Olympus' TTL system and offers wireless master TTL functionality for controlling up to 3 groups of remote flashes. Additionally, it has slow, first and second curtain sync capabilities and runs on the camera's power, so it does not need batteries.
