Nikon is seriously ripping off customers with the MB-D12. However, Nikon does have a sense of humor about it – just go to Nikon USA and see where they ask $616 for this glorified battery case .

I have long been a fan of power packs, if nothing else, it allows me to hold my camera easily and I don't have to worry about losing power.

A great addition to my D800. The fit and finish of the Nikon genuine product is second to none, and I would gladly buy another of these if I end up owning another D800.
