Ops .. maybe my wording is too offensive. I apologies sincerely.
Just to share with you, recently I ask for nikon 24-70 .. when I ask about the barrel jam issue, if thats covered under their shop warrenty, their reply was a strict NO. Then they said manufacturer defect will be covered. That left me wondering how the shop define manufacturers defect in their own context ????
So if you want to get the 24-70, or d600, pls check with them that they are willing to bear the cost for the repair should the common issue like oil on sensor, barrel jam problem ever occure, and written in black and white on the agreement. Its serious cost for the shop or you to bear should it ever happen.
