Godox TT685O Thinklite TTL Flash for Olympus/Panasonic
The Godox TT685O Thinklite TTL Flash is a powerful, full-featured speedlight engineered for seamless compatibility with the Olympus and Panasonic TTL metering systems. Boasting a robust guide number of 197 feet and an integrated 2.4GHz radio transceiver, this flash simplifies the process of creating both effortless on-camera illumination and intricate off-camera multi-flash studio setups. Support for high-speed sync (HSS) and flexible bounce articulation makes it an indispensable tool for event, portrait, and commercial photographers.

Built-In 2.4GHz X Radio System & TTL Automation
Integrated Godox X System: Features an on-board 2.4GHz radio framework that allows the flash to operate as a full wireless master commander or remote slave unit. It boasts an expansive wireless range of up to 328 feet, supporting 32 separate channels and 3 customizable flash groups.

Olympus/Panasonic TTL Integration: Enjoy complete automated synchronization with your camera’s exposure meter. It supports advanced automated modes, including flash exposure compensation (FEC) and High-Speed Sync (HSS) up to 1/8000 second to freeze motion or shoot with wide apertures under bright sunlight.

Optical Master/Slave Functionality: Retains traditional optical pulse transmission sensors to trigger or be triggered by other standard optical speedlights, offering a reliable alternative wireless mode.

High Output & Flexible Light Modification

20-200mm Auto-Zoom Range: The flash head features an motorized zoom coverage of 20-200mm that automatically shifts to match your lens’s focal length. A built-in pull-out 14mm wide-angle panel is included for sweeping wide-angle lens coverage.

Full Bounce Articulation: The versatile flash head tilts from -7° to 90° and rotates a full 360°, granting absolute creative control over light placement when bouncing light off walls or ceilings.

Fine Manual Power Control: When operating in manual mode, power values can be adjusted from 1/1 full power down to 1/128 in precise 1/3 EV increments.
