On the subject of protocols, if you look at existing Pentax radio triggers like the Acon triggers, they don't do much more (it seems) than emulate a dumb hot-shoe extension cable, using WiFi as the data transport between camera hotshoe and flash. Just standard data networking tech at work, not fancy flash protocols. So if the P-TTL protocol hasn't been revised to include radio support, maybe that's not really the road-block for trigger makers.
That's not what I meant. I meant that Shanny's other flashes that have built in radio's won't receive Pentax specific instructions from any of their triggers because they are all either Nikon or Canon TTL protocols. There is no radio built into the SN600FGZ. I'm not even sure in Manual mode if the trigger would fire (does it disable the TTL pins?).
For example, If I mount my Comtrig G430 trigger (Nikon version) on my hotshoe and mount the flash onto the trigger, the Shanny will never fire. It only fires off camera with the Comtrig G430 receiver (flash will also wake up remotely).
However, if I mount my Vivitar 383 Series-1 P-TTL flash to the same trigger, it will actually fire. So again, it seems that however Shanny went about this, they did it their own special way. Probably why they also state that their system will not work with Yongnuo equipment. I can't recall specifically what equipment it was but I do recall them saying Yongnuo is not compatible and vice versa.
