RF60X on V6II Intermittent Auto TTL

1 x RF60X Firmware A01
3 x V6II Firmware Fuji 1.002

Place RF60X on any of the V6II and if detect flash box is empty then only Manual ON available. Sometimes, if detect flash box has F then Auto TTL is displayed. Keep moving RF60X from one V6II to another and sometimes works, sometimes not.

Place Fuji EF-X500 or Nissin i40 on any of the 3 x V6II and always Auto TTL is displayed.

And, please help me understand ... if RF60X is placed on V6II does this turn non-TTL RF60X flash into TTL flash?


  • ... and, I can't seem to use the following set-up:

    i40 on V6II and using v6ii to fire manually. First press on the transmitter V6II turns focus assist led on the then sometimes it fires, sometimes not. Change i40 for Fuji EF-X500 and no problem, fires every time.
  • Wrong firmware on the RF60X.

    Install version 103

    For now, version A01 is for Pentax X-TTL firmware: PEN.A.001.
