If it is dust, that is understandable....but...on a brand new out of the box unit...or should I say 5 of them? On all five cameras I tested....NONE of them had the lens removed after the first time the lens was put on out of the box ( all lenses initially installed with NO battery in the cam). So, again if it is dust...the dust is on the sensor right out of the factory...that to me just shows poor quality control. @LostPatrol...yes, you are correct the spots are more apparent at higher f stops...but I have seen them at f8...so if I have to keeping shooting at f8 or less, I am unable to use the upper 70% of my aperture range. @zhounder...friend of mine has the D100, it's a year old now...he checked his last night...he too has some spotting although minor. Still haven't heard back from Nikon...I doubt that I ever will.

In youth, we learn....with age, we understand.
