Pentax X-TTL - can't get manual flash to work
Camera: Pentax K-5IIs
Flash: Pentax AF540FGZII
What am I doing wrong? I have flashed the V6II twice. I have done a factory reset. But the problems still persist.
1. Manual flash mode. I get dark frames on all shots. I can tell the TX is controlling the RX from the LCD screen. But 1/1 and 1/256 have the same results. Also at 1/1 the flash is not firing at full power.
2. TTL mode. Dialing in minus compensation does nothing to the result. Dialing in plus compensation will result in brighter exposure. Also it is not linear. +1.0 is supposed to be twice as bright but it seems to be more like 1/3 stop.
