The PIXAPRO ST-III Plus is the next evolution of the ST-III TTL wireless flash trigger.
Five Dedicated Groups
The PIXAPRO ST-III Plus Wireless TTL Flash Trigger 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.
Easy To Use
The ST-III + Wireless TTL Flash Trigger also features a re-designed scroll wheel, now placed on the left-hand side of the trigger for improved accessibility.
100m Transmission Range
The PIXAPRO PRO ST-III + TTL Flash 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 dont need direct line of sight.
Advanced Features
There is also a œScan 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.
5 Individual Groups Available
The PIXAPRO PRO ST-III + Wireless TTL Flash Trigger allows up to 5 Groups to be individually set to either TTL, Manual, or Off.
Option To Mix TTL & Manual
You can also mix TTL and Manual Groups if needed, which makes the ST-III + system very versatile.
32 Seperate Channels
The ST-II+I Wireless TTL Flash Trigger 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 others lights.
TTL, HSS & Pre-sync
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 cameras sync speed.
Bluetooth Feature
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.
PC Sync Cable & USB Type C Port
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.
