A few lens-changing tricks that should reduce...

the occurrance of dust on the sensor and mirror:

1. (obviously) Try and find an area as free of dust and air motion as you can to change lenses.

2. Keep the back element of the lenses clean (at least with a blower) and switch covers from one lens to the other so as to minimize the time the back end of the lenses are uncovered.

3. Always keep the camera body lens opening pointed downward when changing lenses, and keep it open only as long as absolutely necessary to effect the change. This can be a bit cumbersome on times, but does pay off in the reduced dust incidents.
