P-TTL with V6 II
I'm using the V6 II with a Pentax 645Z and Pentax AF-540FGZ flash.
I'm trying to use my flash off camera with 2 V6 II units in full P-TTL mode. Whether I set the TX in TTL passthrough or not, the flash behaves the same with regard to power levels. That is, I don't get full automatic P-TTL flash control. I still have to set the power levels. Am I missing a step in the setup somewhere?
