Thanks for the info. For anyone who is interested in going wireless the Neewer FC-16 works directly connected to the drop controller unfortunately it doesn’t appear to be so well made as the RF-603 and they are not compatible with each other. So I’m considering buying the Neewer NW570 2.4GH flashes as I’m not sure if the FC-16 would be able to trigger the Yongnuo YN-560 Mark III’s.
Neewer, Triopo, and Meike all appear to be the same. If anyone has ever used a FC-16 trigger for a Yongnuo YN-560 III flash please let me know
