PRO ST-III Plus 2.4GHz TTL Flash Trigger with High-Speed Sync & Bluetooth

The PIXAPRO ST-III Plus 2.4GHz flash trigger is the next evolution of the ST-III 2.4GHz TTL flash trigger. The PIXAPRO ST-III Plus now features five dedicated group buttons, enabling you to quickly and easily select the flash group that you desire, and adjust the power of that group, without having to scroll to find the group you are looking for. The ST-III + also features a re-designed scroll wheel, now placed on the left-hand side of the trigger for improved accessibility.

The PIXAPRO PRO ST-III + trigger has a transmission range of approximately 100m in an open area, and since it uses 2.4GHz radio waves as opposed to Infra-red to communicate, so you don’t need direct line of sight. There is also a “Scan for Best Channel” function, which scans the airwaves to help identify the best channel(s) to use that will give you the least amount of interference.

The PIXAPRO PRO ST-III + allows up to 5 Groups to be individually set to either TTL, Manual, or Off. You can also mix TTL and Manual Groups if needed, which makes the 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 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.

The PIXAPRO PRO ST-III + has a Bluetooth feature, which enables you to use the trigger in conjunction with an app, allowing you to control your flashes from a smartphone or tablet.

It also features a PC sync cable socket enabling it to be used to trigger studio strobes, as well as a USB Type C port to enable you to update the ST-III +’s Firmware as new technologies become available.

The perfect solution for the busy photographer who requires a reliable TTL radio trigger system. Available for Canon, Nikon, Sony, Olympus, Panasonic, Fujifilm and now Pentax.
