Trigger V6IIs with V5
May it seems like a really stupid question, but I'm new in the whole cactus world. I already got a V5 Duo for my Sony A7 to trigger my Canon Speedlight. Now a purchased a V6IIs to trigger my Sony F60M, but it seems like I can't Use the V5 as TX to trigger the V6IIs (RX). Am I right, do I need to purchase another V6IIs?
Thanks for your Help!
