Bought mine in mid december after reading all the doom and gloom scenarios from the arm chair experts on another forum. My digital learning curve has been Fuji S2 Pro, D200, D300s and now the 600 as I wanted to return to full frame capture. My 14mm f2.8 is now 14mm again. The D600 is a great camera and I have no regrets.
Cold weather photography makes a VR lens your best friend. Think violent shivering. :-)
