I had long can not persuade me to order the YN-622N. The reason was that a convenient setting just a master flash on the camera-side transceiver was possible. Have now ordered with the YN-622N-TX and am excited about the combination. After some familiarization, I am positively confirmed. Only the keys are mounted a bit inconvenient, you can quickly adjust them accidentally. But if you know, not really a problem. Also for the YN-622N is true what I had written in the YN-622N-TX recession: the chinenglisch / engnesische Manual is available for some acclimatization and you can imagine what we are talking is when one is with i-TTL flashes and Nikon cameras has employed.
