100m Transmission Range

Easy To Use

Each group can now be easily accessed via the five-dedicated group selection buttons, located at the side of the LCD screen.

Mix TTL & Manual

You can also mix TTL and Manual flashes together in one lighting set-up.

Advanced Features

One of the PIXAPRO PRO ST-IV’s new features is its TCM function, which enables you to take a shot in TTL mode to attain the correct exposure and then convert the TTL power levels to display on the LCD as Manual power levels, all from the touch of a single button.

Supports TTL, HSS, Multi-flash
