Supports TTL, 1/8000s HSS, manual, optical slave, S1/S2 optical control, stroboscopic flash, and flash exposure compensation. A high GN58 guide number allows long distance flashes.

The rear curtain sync allows the flash to fire right before the shutter closes, so you can get sufficient exposure and smooth light trails behind the subject.

With optical transmission function, NW645II-C works as a slave unit when it's on the same channel and group as the original master Speedlite.

1/128–1 adjustable flash output suits various light conditions. The 5600K±200K color temperature provides a natural color.

Flash head can tilt at -7°/90° and rotate 270°. Diffusers broaden flash output and reduce shadows.
