I'm going to be doing an event shoot at a Marriott and I'm thinking to use optical, since radio isn't reliable. Back to optical! I own 5 radio Canons and they're useless.
It's not that they "fail". They succumb to RFI in a very busy band. They work exactly as they were designed - which includes no auto "re-start" capability in the face of RFI.
Gwynne, as of now it seems that there is no Canon hardware/software solution, and Canon as a company has its head buried deep in the sand. I have 5 Canon flashes which are pretty much useless. As you have perhaps read, this is due to the congestion...
