I’m very interested in the new PW units - however when I asked the local Nikon dealer about the CLS availability they said probably never! I invested in Nikon CLS and have 2 SB-600, 1 SB-800, 2 SB-900 and 2 SU-800 units. I also have a photogenic studio strobe that I have attempted to use with the Nikon CLS strobes - with very mixed results. The Nikon CLS system is superb … when it works! However using today’s standard PW to fire them disables the CLS and requires manual settings for each strobe, so I have been waiting for a way to combine both CLS and non-CLS - as well as extend the range and dependability of CLS in demanding situations. Keep us posted!
