HSS with Pentax
Hi
I use the Pentax system: a K-70 body with an AF540FGZ. I was looking for something that would allow me to do off-camera HSS and learnt that Cactus V6-II was my best option. Since I am new to the Cactus system, I have a sort of a stupid question. To be able to fire my AF540 off-camera, I need *TWO* V6-II transceivers, one mounted on my camera hotshoe and the other fitted to the flash-gun off-camera. Is that right?
Thanks

You need one unit on the camera, and one unit for each off-camera flash. Only the RF60x has a built-in radio receiver, all other speedlights need their own receiver attached.
Thanks for any advice
Why not add a V6II receiver and get power and zoom control over the AF540?
I don't see the point of using an infrared trigger. You might as well then just use a P-TTL HSS flash as a trigger and not use any V6II at all.
Direct radio control is not supported as paulster wrote.
Trigger stacking is not officially supported by Cactus but has been working until firmware version V1.1.006. So using this firmware version (and a basic Godox trigger and possibly the "Nikon" flash profile), you should be OK. Many Pentax users got this to work.
I hope that Cactus can iron out the remaining Pentax issues in V1.1.009 with a future firmware release so that one isn't forced to use an old firmware version.
