btw, the Nikon version (the SN600SN) is a variation of the SN600SC for Canon which was one of Shanny’s earlier flash models. It has the same locking feature as Canon flash... and no it is decidedly not made by Younguo, it has a much higher build quality...
I have a half dozen of these units which I use with the Phottix wireless radio trigger/receivers... simply set the Shanny SN 600SN to i-TTL an Bob's your uncle... You then can run remote Shanny SN 600SN's entirely from you Phottix trigger...
The Shanny SN 600SN is a Nikon SB910 clone...
I downloaded the Shanny SN 600SN User Guide long ago...
Keep searching the web it's out there...
Oh, I no longer use the Nikon SB910 since the Shanny SN 600SN has a more powerful flash and a shorter recycle time...
Great unit, I gang mine together in a four flash cluster... HHS up to 1/8000 got to love that!
So if you want to see a review of the Shanny SN 600SN comparison against the Nikon SB910 and the cheaper Yongnuo 568 (It is lengthy 45 minutes) and clearly showcases the differences between these vendor's units...
https://www.youtube.com/watch?v=wGwmXwAAcRUOne awesome feature of the Shanny SN 600SN unit is it has a rubber cover on it's attachment foot to weather seal when attached to the hot shoe.... It's build quality approaches (and in some ways betters) Nikon's SB 910
