D400, a very good way to get Nikon attention
Nikon like all the well regarded company like to keep their reputation/images as good as possible. If you email them, only them know that you did and 1000's of email will have no impact on them. What would have some impact on them....social media! Just post a message on Nikon facebook page :
I just did it and hope that 1000's of peoples will do it. Believe me, this worked by the past and can work again.
Let see if you realy wan to send a clear message to Nikon !!
