Panasonic GH5 with Godox tt350o flash

... working in a large urban hotel, I've found radio interference from nearby wifi, wireless mics, and God knows what else to seriously decrease the range and also make triggering very unreliable - like, only 20% success in a medium conference room. This is with Adorama's Zoom Mini (TT350) on-camera and a pair of Zoom Li-on R2s (V860II) on stands. On the theory that it would have greater radio power than the Zoom Mini, I got an R2 (X1). That had no problem triggering a pair of Zoom Li-ons 100' away in a large ballroom.

Interesting. It's pretty clear the X1T is all around a better transmitter unit to use than the TT350.

I posited a theory on POTN that the use of the new wireless ID code feature might help with RF interference, but was pretty much voted down by more tech-savvy voices.  They're probably right.

However, testing at home shows that a shutter press on my GX7 with R2 mounted will trigger the Zoom Li-Ions only if the camera is in AFF or AFC mode, not in AFS. Weird. All firmware is up-to-date. One Zoom Li-on can trigger the other in any AF mode, so this odd behavior is unique to the R2.

That is weird.  I'd mention it to brands@adorama.com (Flashpoint support).  They may just send you the email reply equivalent of a shrug, but at least they'd know.

FWIW, at home, the Zoom Mini reliably triggers the Zoom Li-ons in any AF mode.

My old 433MHz R1 triggers always worked perfectly - though they don't support TTL - so these will be my Plan B for high-interference situations until the R2 can be made to work properly and reliably with all my GX7's AF modes.

I'm hoping that they're working on fixes for the -O triggers. The fact that all the other flavors have had XPro transmitters either released on listed for pre-order at Adorama, but that there's been complete radio silence on the XPro-O is making me think they've had to go back to the drawing board to more completely suss out the four-thirds hotshoe protocol or Panasonic variants of the same.
