I just picked up the Yongnuo YN568EXIII speedlite to do High Speed sync with my D600. I have HSS compatible triggers (YN 622N). Read the manual on the flash and it says if camera is set to do HSS then the Flash will work in HSS as well. The Auto FP option is selected on my D600. No other settings seem to be required but the flash will not fire in Manual mode at all using triggers. It will fire in iTTL mode or commander mode using pop up flash but will not do High speed sync. Any suggestions on how to get it to work HSS with my camera? I have used these triggers before with Nikon SB800 speedlite successfully in HSS.
