18 Modus 600RT

Flash Mode - TTL Autoash

This ash has three ash modes: TTL, Manual (M), and

MULTI (Stroboscopic). In TTL mode, the camera and the

ash will work together to calculate the correct exposure

for the subject and the background. In this mode, multiple

TTL functions are available: FEC, HSS & second curtain

sync, modeling ash. These can be controlled with the

Modus 600RT or with the camera’s menu screen.

* Press < MODE > Mode Selection Button and three ash modes

will display on the LCD panel one by one with each pressing.
