Glad to hear that since I just packed up my D600 to be sent to Nikon. Bought in december at good price and never played with it until a few days ago. Getting "Err" message consistently with all lens tested when aperture wasn't wide opened in all modes. Very strange. Wide opened it functioned normally. For example, in Aperture Mode I could shoot low and high continuous as long as lens was wide opened but if I changed f-stop, only single shot and ERR flashing. Would need to turn off to clear. Did many 2 button resets, resets of shooting and custom, removing battery and changing memory cards. Did the same tests with d7000 and it worked fine, no errors. I need it back by mid-july for safari. Hope I have your luck.
