D800 wifi adapter
This is one of the really severe weaknesses of the really really great D800. A simple to use and affordable (100-200 bucks) adapter that works with smartphones, tablets and notebooks should be included in Nikon's camera system. Compared to old days accessories to Nikon cameras are really expensive and very often with little added value compared to third party solutions. The wifi-solutions for the D800 are simply rediculous for such a giant brand like Nikon.
The consumer camera solution would do just fine for many purposes. The more powerfull wifi solutions should be optional and yes in this regard high prices would be justifiable.
