The PIXAPRO PRO ST-III C equivalent to Godox's X1 TTL is a 2.4GHz Radio flash trigger system capable of transmitting TTL information designed for use with Canon EOS, or Nikon cameras and TTL Compatible flashes. The PIXAPRO PRO ST-III trigger set 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 slave systems.

As well as the traditional  A:B C ratio style interface, the PIXAPRO PRO ST-III also has a full GR Group style interface allowing up to 5 Groups to be individually set to either TTL, Manual, or Off. You also have the ability to mix TTL and Manual Groups if needed, which makes the PRO ST-III system very versatile. The ST-III system also has 32 separate channels, which enable you to use your ST-III trigger system in the vicinity of other photographers, without fear of accidentally triggering each other’s lights.

The PIXAPRO PRO ST-III supports TTL, HSS (High Speed Sync) and even has a HSS Pre-sync Timing Adjustment feature, which is great for those times where you need to increase your shutter-speed beyond your camera’s sync speed.

As well as being TTL Radio trigger system, the PIXAPRO PRO ST-III C can also be used as a wireless shutter release for your camera. It also features a PC sync cable socket enabling it to be used to trigger studio strobes. There is also a Micro USB port to enable you to update the ST-III’s Firmware as new technologies become available.

The perfect solution for the busy photographer who require a reliable TTL radio trigger system.
