[nwbcc] Sensor cleaning

[Des Finkenzeller]

Marilyn,

I've used the techniques described previously and without fuss or drama, and
I've only had to do it twice in maybe 18 months.

I always take measures to reduce the chances of getting dust on the sensor;
a) I make sure that the camera is turned off - you should do this anyway as
you may get problems otherwise.
b) I prepare for the operation so that my new lens is ready to be attached
before I remove the old lens.
c) I keep the lens cap on (but unscrewed) until I am ready to attach the
lens to the camera body.
d) I keep the camera body pointing down so that no dust can settle on it.
e) I complete the operation as quickly as possible to reduce the time the
sensor is exposed to the environment.

I use Canon L Series lenses which are supposed to be their professional
quality lenses. These lenses are supposed to have some mechanism in them
(might be internal focusing?) which reduces the bellows effect which can
occur when using zoom lenses. Some cheaper lenses have a tendency to suck in
dust particles when you zoom the lens.

Cheers
