Usually dust gets inside between the front and the rear element group, the space where the aperture blades is. You can get there from the front or from the rear. >From the front, you need to unscrew the retaining ring (#1), 3 screws (#2) and >then the front element group itself (#3). Use a rubber blower to blow off the dust and job done. http://www.pbase.com/wlachan/image/41193715.jpg 2 things you need are low strength threadlock (threebond 1401) for the 3 screws (#2) and the proper lens wrench. The retaining ring itself doesn't require threadlock or you won't be able to get it off again in the future. http://www.pbase.com/wlachan/image/41194481.jpg To work from the rear, you only need the wrench to remove the rear element group. However, due to the tight working space, it requires more skill to work properly w/o leaving tool marks. A piece of rubber be used instead of the wrench depends on the situation in both cases.
