Godox TT685S


Godox TT685S is a fully-featured TTL flashgun, much like the older model TT680 but with an addition of built-in 2.4GHz radio receiver. It is a part of Godox’s long awaited 2.4GHz TTL radio flash system, now accompanied by the X1-S TTL triggers. Godox flash system is one of the most comprehensive radio flash systems currently available. Whats impressive about the Godox flash system is not only the large range of lights, with full compatibility between remote manual and TTL equipment, but also intercompatibility between Sony, Canon and Nikon TTL compatible versions


Godox TT685S | Speedlite Flash for Sony

Godox TT685S is a next generation flash released by Godox. It features TTL auto flash for Sony DSLR and Mirrorless cameras and optical triggering with even illumination and a stable output. Using 2.4GHz wireless, you have an operating range of up to 100 meters. It can also be used as master flash to trigger other Sony speedlites in TTL or manual mode, or it can work as a slave flash in Sony wireless lighting system (WL).

Godox TT685S is a fully featured on-camera TTL speedlite flash. It supports FEC, FEB, FE Lock, Rear Curtain Sync, Modeling Flash, Control with Godox X1T-S wireless transmitter etc. TTL mode helps you achieve a correct flash exposure even in complex light-changing environments. In TTL mode, camera and flash work together to calculate the correct exposure for the subject and the background.

Build quality is great. Godox like their competitors have seriously upped their game in terms of the plastics used.  Compared against the genuine Sony flash unit, it feels just as solid. TTL metering is really reliable. Godox’s flash exposure is identical to the Sony HVL-F60M.
