Olympus FL-LM3 Flash

The Olympus FL-LM3 Flash is a compact, on-camera lighting accessory specifically designed to accompany the OM-D E-M5 Mark II, and also compatible with other Micro Four Thirds bodies including the E-M1 Mark II/III, E-M5 Mark III, E-M10 Mark III, E-M1X, OM5, and PEN-F, giving photographers a dust- and splash-proof flash option for fill lighting and quick setups.

The flash offers a guide number of approximately 29.86 ft. (9.1m) at ISO 100, with coverage suited to a 12mm Micro Four Thirds lens (equivalent to 24mm in 35mm format). It’s fully compatible with Olympus’s TTL system for automatic exposure control, and the flash head tilts upward 90 degrees while rotating left and right 180 degrees, giving photographers bounce-flash capability for softer, more directional lighting off a ceiling or wall. Flash modes include first-curtain sync, second-curtain sync, and slow sync, with a maximum flash sync speed of 1/250 second.

Beyond serving as a simple on-camera flash, the FL-LM3 also includes wireless master (commander) TTL functionality, letting photographers trigger and control other compatible off-camera flash units directly through the camera’s menu controls, along with Multi (stroboscopic) mode capability for firing the flash multiple times within a single exposure.

Build quality includes a dust- and splash-proof plastic construction matching the ruggedness of compatible OM-D camera bodies, and the flash draws power directly from the connected camera rather than requiring its own batteries. It’s remarkably compact and lightweight, measuring approximately 44.3 x 33.5 x 52.5mm and weighing just 51g, making it an easy, unobtrusive addition to a Micro Four Thirds camera kit.
