Although you make good points about this product... I would never
recommend using compressed air in the chamber of a digital camera. If
you use an aerosol/compressed air it becomes very easy get liquid
proplent on the CCD. I also usually recommend against using a brush of
any kind... as the bristles can damage the extremely delicate filters
that sit overtop of the sensor. Best idea - a blower... which you can
get for a few bucks from any camera store.


Better to vacuum. Blowers move things around and drive particles ever
deeper into the camera to cause future problems or merely come back and
repeat what they were doing. A very low pressure vacuum, mind you, with
a light brushing to dislodge particles.


When you vacuum, where does the air come from? Yes, I know it comes from
inside the camera. When you pull that air out, it gets replaced with air
from somewhere else. i.e. You don't actually create a vacuum inside the
camera. Why wouldn't this replacement air also contain dust? I would
think it would, unless you were doing this in a dust free room.

So, why is vacuuming any better than blowing?
