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' / 60 m 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.
