Yes, you've got to love this lack of standardization in the photo industry. In some ways I miss the old M42 lens mount...
But you are right. Even with the Sekonic / Pocket Wizard integration, I can't use all of the zone settings on my Einstein 640 lights, if I want to trigger them with the flash meter radio. I'd have to buy the Paul C Buff triggers, but then I couldn't use them with my Nikon Speedlights.
