I just got a set of the Yongnuo RF-600 TX and 4 receivers which work well with my 60D and 5D3, EXCEPT when I have either camera in live View, and then they just don't work.
When Live View is switched off, using the OVF, they work perfectly, but when I switch to Live View, it won't trigger the falshes.
Anyone have any ideas as to why, and how to get around this problem?
