That sucks. How did you discover the dust? Were you actually looking for it or did it just become prominent on images?
Not that I want to find any in my units but I'm just being curious.
If I found dust on the sensor, I'd open the sucker up and get rid of it.
I go to Independence Hall all the time here in Philly. In the restrooms they have those new fangled forced air hand dryers. Well, I put the camera in there up and down for around 10-15 seconds whenever I have to take a...uh, you know.
So far if there was any dust, it's gone.
