Recognizing of Pentax flashlights

Firmware PEN.A.003 (triggers was resetted into factory settings after updating firmware )

Trigger doesn't recognize Pentax 540 FGZ with head tilted .
In the same situation (head tilted or swiveled) Pentax 540 FGZII is recognized correctly.


  • Yes, flash head must NOT be tilted - it must face forward.

    Unfortunately, there's nothing we can do about that as it's a Pentax thing.
