Yup. Apparently, however, on one or the other of the most recent
cameras the sensor is actually jiggled by the cleaning routine and
the dust falls off.
But this guy is out in the arctic/antarctic I believe Karl mentioned.
Trips to google won't do him much good there.
Which is why I recommended he come prepared, for which it's also too late.
My camera goes to the cleaner at least 4 times a year and comes back
clean. That lasts about a day before dust has invaded the sensor
again. I don't even have to change the lens to get dust in there.
After three months I'm stamping out 50 or 60 spots of dust on each
keeper and it's time to go back for a renewed lease on sensor
cleanliness.
This is life for digital capture unless one has one of the highest
end cameras with all the seals that keep out water. From there it's
only the lens changing that allows dust to enter and get caught on
the sensor.
So one needs a body for each lens after that.
