The scratch right below the reflecting mirror on D600.

Haha yah... From the fryingpan into the fire : P

But for what i can make of it, the problems now surfacing with the D600 seem to be the result of design flaws, where the D800 leftfocusissue was a mere production problem.

Maybe the problem turns out to be less bad then i anticipate, but i know for sure my sensor was a mess right out of the box and i still can return it with no further fuss. Better safe than sorry.

I agree on the idea of individuals reporting the problem to Nikon, if only to help them identify the magnitude of these issues...
