I have Yongnuo YN-622N-TX and a couple of YN-622N transceivers for my flashes. I've heard that the TX unit can be used as a remote shutter release. Alas, Google is not my fried in this (perhaps I don't know what question to ask), the only thing I found that this is somehow related to LS-2.5 release cable.
How do I use the TX to remotely release the shutter on my D500?
