I bought two D600, almost two years ago. They were both sent to Nikon for repair. Recently, I found that they where more dust than usual on the sensor. I decided to send them to Nikon and after a short conversation with the service manager, they offer to replace both cameras with the brand new D610 with six month of warranty. That was a surprise to me, I expected a shutter replacement not a camera replacement. Also, the cameras were shipped, with all the accessories, including batteries and chargers. [FA]
