I am shooting with Canon 7D Mark II and I am currently trying to get into the flash photography. I am still working on a budget so I started with two Yongnuo YN-560IVs and a YN-560-TX transmitter.
I am shooting lots of sports and the first time trying these flashes I realized that my flashes won't fire when I place them farther away. I need the flashes to fire from 15m-20m. And I need triggers that can fire my flash even it's placed behind some subject.
I am thinking about buying wireless triggers, but I am not sure which ones to choose. I was looking at the Yongnuo YN-622C TTL, but read elsewhere that it's not compatible with my 7D Mark II. I am not sure what to look for to get triggers that will work with what I have that will do what I need.
Also I'm not sure if I can use my YN-560-TX controller to communicate with transceivers or do I need to buy a wireless flash controller instead (mine says manual)?
