The charge attracts
the dust particles to the brush, which once you remove the brush from the
camera are expelled by pushing the button, which spins the brush. Beware of
companies selling ???artist??? brushes for sensor cleaning. Artist brushes sweep the
dust off the sensor and you run the risk of scratching the sensor.
TIP
When you change lenses, you run the risk of getting dust
on the image sensor because the current to the sensor
can act as a dust magnet. Dust on the sensor will show
up as specks on your image. You can reduce this risk if
you turn off the camera prior to changing lenses. It??™s also
a good idea to change lenses in a sheltered area to avoid
a gust of wind blowing dust into your camera. You should
also point the camera downward when changing lenses
so that any loose dust will fall out of the camera.

Protect Your Camera Lens
If you own a digital SLR, consider purchasing a skylight or UV (ultraviolet)
filter for each lens you own, and leave it on the lens at all times. The filters are
relatively inexpensive and will protect the front lens element from damage.
