Recent Experience with Nikon Product Service (phone) regarding D600 Sensor Problem

+1.  My game plan for lens purchases has completely changed with the anticipation of switching brands in the future.

As far as the class action suit goes, I believe that there is far more chance of satisfaction if individuals look into their local "small claims court" with low cost legal council.  I know different juristictions have different guidelines as to the dollar limit.  If Nikon is forced to send a representative to each and every small claims hearing, they may soon start settling instead.  But I still maintain that the great equalizer is You-Tube and a well organized campain of well documented contributors.
