Product Information
Description

The PIXAPRO PRO ST-IV (equivalent to Godox's XPRO) a 2.4GHz TTL Radio flash trigger system capable of transmitting TTL information between your camera and compatible flashes. The PIXAPRO PRO ST-IV trigger 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.

The PiXAPRO PRO ST-IV transmitter features a large backlit Dot-Matrix LCD display, with a new and intuitive user-interface. The ST-IV now gives you the option of working with up to 5 groups (A, B, C, D and E) of flashes simultaneously. Each group can now be easily accessed via the five-dedicated group selection buttons, located at the side of the LCD screen. You can also mix TTL and Manual flashes together in one lighting set-up.

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.

The PIXAPRO PRO ST-IV supports TTL, HSS (High-Speed Sync) Rear-Curtain sync and stroboscopic multi-flash. It also a USB Type-C port to enable you to update the ST-IV’s Firmware as new technologies become available.

The perfect solution for busy photographers who require a reliable TTL radio trigger system, with a quick and intuitive interface.

 

Features:

  • Large Dot Matrix LCD Screen Displaying 5 Groups
  • 5 Individual Dedicated Group Buttons
  • TCM Function – TTL – CONVERT – MANUAL
  • Built-in Zoom Controls
  • Global Adjustment of Group Power Levels (ALL Button)
  • Large Graphic Menu System with Multiple Custom Functions

Questions & Answers

Answer:

The ST-IV trigger can be used with our PRO AC receiver, however this will have to be our 2.4GHz version which can be found here; https://www.essentialphoto.co.uk/product/pixapro-2point4ghz-pro-ac-wireless-16-channel-radio-flash-receiver-only/ This will not work with our first generation of this receiver as it operates on a different frequency.

Answer:

The ST-IV trigger can be used as a remote shutter release, however, you will also require an ST-III receiver in order to do so.

Answer:

The first option is best suited for times when you are shooting by yourself. If you have multiple shooters using the same group(s) of lights in this mode, the settings on the lights will change depending on which shooter presses the shutter button last.

The Second option is useful for times when more than one photographer is triggering the same flash group(s) with different cameras. In this mode, the settings on all of the ST-IV triggers will automatically all update themselves, depending on whichever settings were last changed. This mode ensures that all the settings are the same across all ST-IV triggers in the same group.
PLEASE NOTE: The batteries will drain quicker in this mode since each ST-IV unit is constantly communicating with one another.

The App option is for when you are using the phone APP to control the flashes.

Answer:

Unfortunately this trigger will not allow you to use TTL with the CITI600 manual version, in order to use TTL with this trigger you would need to use our CITI600 TTL.
