QUOTE=ageha;8824948]You can run into the same issue with a D610, it just happens. At least the D600 gets the cleaning for free. On Flickr are D610 users with more sticky specs on their sensors after a few weeks than my D600 shows after over one year without any wet cleaning and still on the original shutter.
Is it can, will or most likely with the D610. I don't see any vehement complaints here or elsewhere as with the D600.
The free cleaning is after one year of ding dongs here, in America, elsewhere. And it only came about when the "giant" steps in & raise its voice.
Not sure how you measure one week's dust on D610 for comparison, from photos posted on the net.
The issue about dust &/or rather oil spills? In the china video, they happen there & then after some clicks.
Anyway, as I said, look forward to D620, not backwards.
