The Godox TT350C TTL Speedlite is a compact flash unit specially made for Canon digital SLR cameras. It features a 2.4 GHz X radio system, which supports 16 channels and 3 groups. The wireless flash can be set up as a master as well as a slave, and be triggered from a distance 30 m under the RF method and from 15 m under the optical-pulse method. Additionally, it has a 3.5mm port for synchronizing the camera or trigger through wired connectivity. The flashlights up all subjects within its range, thanks to the guide number of 118 ft at ISO 100 and at 105mm position. The TT350C prepares itself for the next shot in as little as 0.1 seconds and its shortest flash duration is 1/20000th of a second. The flash can rotate a full 270° and tilt from -7° to +90°. It runs on two alkaline or NiMH AA batteries that enable it to fire up to 210 full-power flashes.
