My D600 I have for a few months and have already almost 2k images shot. As far as I use exclusively with Nikon D600 28mm f 1.8g lens and am more than satisfied with this combination.
The bezel on my lens goes up f 16 and since I also see some particles on the sensor. The thing is, aperture 16 I set a few times, and I do not think so photographers will go to this panel number. For those who still f 16, 22 and so on need, just leave your sensor professionally cleaned and begin at last to photograph ...
The camera with a good lens provides excellent pictures and if you are searching only pixelpeep and shortcomings in your device, you miss many beautiful moments that could take you!
Conclusion: I love my D600 and congratulate others happy owner. Also, I wish you much fun while photographing !!!
