Pixel Enterprise has released some information on their new TTL control trigger the King Pro. I am pretty excited about the release of these new triggers. So far they just have information on the Canon models but hopefully the Nikon ones will not be far behind.
Pixel 3rd Generation Wireless TTL Flash Trigger King Pro for Canon is suitable for Canon cameras. Using digital FSK 2.4GHz wireless remote control. Compared to the previous two generations, the effective remote control distance improved significantly to 300M or above. Also, we have made a very big change in the functional operation.
