Originally posted by Smoke665 That's part of the confusion, I keep seeing some don't work with HSS some don't with PTTL. I'd looked at a use AF360fgz.
With Pentax HSS is a P-TTL mode only. I am sure that applies for third party flashes too

I use two Af540 II and two Cactus RF60X. When combined with the Cactus radio triggers, I can fire all of them in P-TTL mode (with compensation) or in manual mode, controlled individually directly from the radio transmitter on the camera hot shoe. They work extremely well together.
I have a feeling (someone correct me if I am wrong) that the Cactus RF60X will not work in P-TTL on its own when placed directly on the camera.
