The first time I inserted a compact flash card into my brand new D4, the camera started to smoke. It turned out to have a bad pin.
I sent it to Nikon , and of course they blamed me, saying that something happened to the camera causing the pin to bend. They wouldn't accept the fact that it could have been a manufacturing problem. I've been using digital cameras since the D1 and have had several digital nikons and never had one card problem. I finally paid the close to $400.00 price for the repair.
Not more than two weeks after getting my D4 back, the led viewfinder became in operative along with the shutter not working properly. It's once again in the shop, this time it's being repaired under warranty.
My $6,000.00 camera has spent more time at Nikon repair than in my possession. WTF ???
