Flashes don’t stay synced anymore!
I’m shooting canon R5s and using canon 600exii rt flashes — all of the sudden they will NOT stay synced for more than a few minutes. Ive tried scanning for channels and changing multiple times, changing the ID # & channel, scanning again near band or Dj equipment - I’m at a loss. Google is not much help — turning them off and on again will sometimes work but 5-10m later they are red lit again & unsynced. It’s very frustrating when shooting for work and missing critical shots because the light suddenly changes mid moment :/ is canon nerfing these to push buying the ones they just put out that are $1200 each?! I’d really rather not after just upgrading my camera bodies and lenses last year. Does firmware get updated in these? any advice welcome, I’m at a loss here.
