Are you "anti-dust control system" types suuurreee the that they
aren't needed?
It has been 9 months since I cleaned our 20D and 350D and still not
dust that is a problem. This may be because I rarely shoot slower
then f/16. I use Prime lenses a fair bit so I am always changing
lenses and I do this on the beach, and still no dust problems. Why
some people seem to have so much trouble is a bit of a mystery.
