The PIXAPRO PRO ST-IV 2.4GHz Flash Trigger Wide LCD Display (equivalent to Godox's XPRO) a 2.4GHz TTL Radio flash trigger system capable of transmitting TTL information between your camera and compatible flashes.
100m Transmission Range
The PRO ST-IV 2.4GHz Flash Trigger Wide LCD Display has a transmission range of approximately 100m in an open area, and since the transmitter and receivers use radio waves as opposed to Infra-red, you don’t need direct line of sight and is not affected by bright sunlight which can sometimes cause problems with optical flash trigger systems.
User-friendly Display
The PRO ST-IV 2.4GHz Flash Trigger Wide LCD Display features a large backlit Dot-Matrix LCD display, with a new and intuitive user interface.
Multiple Group Options
The ST-IV Flash Trigger TTL now gives you the option of working with up to 5 groups (A, B, C, D and E) of flashes simultaneously.
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
The PIXAPRO PRO ST-IV Flash Trigger TTL Wide LCD Display supports TTL, HSS (High-Speed Sync) Rear-Curtain sync and stroboscopic multi-flash.
Type-C USB Port
It also a USB Type-C port to enable you to update the ST-IV’s Firmware as new technologies become available.
The PRO ST-IV Flash Trigger TTL is the perfect solution for busy photographers who require a reliable TTL radio trigger system, with a quick and intuitive interface.
