Offering full support for Olympus/Panasonic TTL and a built-in 2.4 GHz radio system, the Godox TT685O II Flash makes it easy to create both simple and elaborate lighting setups. A powerful and effective lighting tool, this flash features a powerful guide number of 197' at ISO 100 with a zoom range of 20-200mm. The TT685O II operates as a full wireless master or slave unit with TTL functionality, and for maximum versatility this updated unit tilts from -7 to 120° and rotates 330°, giving you more flexible flash angles and a more efficient lighting setup process. Also featured is a new and unique TCM (TTL Converted to Manual) function, which allows for instant conversion from TTL to manual mode. This function helps you lock the proper exposure value and is useful for quickly determining a good starting point for setting external flash units in manual mode. For ease of use, an easy-to-read rear LCD panel illuminates your flash settings, and the flash includes a 2.5mm sync port for basic wired connectivity.Using the 2.4 GHz Godox X wireless radio system, the XProO TTL Wireless Flash Trigger can be used to effectively and reliably trigger flashes from up to 328' away, and when used with compatible flashes and receivers users will have the added benefit of remote power control. This model is compatible with Olympus/Panasonic's TTL system, including support for high-speed sync up to 1/8000 second, and offers advanced control options along with settings for working with system-specific features. For ensuring maximum reliability and control, users can set up 16 groups on one of 32 channels and can then access 99 wireless ID settings for limiting interference from other nearby systems.





In addition to basic manual and TTL control modes, other settings are available, including stroboscopic flash and second-curtain sync. Users can adjust flash exposure compensation from -3 to 3 EV as well as wirelessly control the modeling light, zoom setting, and more. For using the XProO with other camera systems there is a 2.5mm sync port that supports triggering via a wired connection. Also, a USB Type-C port is present for firmware updates and the devices run on two AA batteries for convenience.
