Originally posted by rawr I think this image sums it up. It can transmit to some strobes and speedlights directly via radio, and indirectly communicate with other strobes via another radio receiver/trigger:
and this table:
I've seen that image, but there was no info about what that receiver is. The table says its might be a XTR-16, but clicking on that on the website brings me to a product that looks nothing like the receiver in that image.
And when I look at the flashes like the V860ii that doesn't need a reciever, I don't see any Pentax compatible ones - only Nikon, Canon, Fuji, Sony, Olympus/Panasonic.
Nothing is written in a way that makes sense! Like: "Note: The range of support functions: The functions that are both owned by XProP and flash" -- That isn't a sentence
