I vacuumed the dust out of my SEL 18-200mm lens.

Re: brilliant post. Any less-than-$200 dollar vacuum that would work?

I think that greater emphasis needs to be placed on the possibility of sucking dust into the lens ! That is the way in which dust gets into the lens in the first place.

I would suggest placing a vacuumed microfibre cloth around the lens when performing these procedures having first vacuumed the general exterior of the lens. Houshold interiors abound in small particles of dust shed from carpets & textiles & if you were unlucky you could end up with more lens dust than you started with

you are dead right, the air being sucked out must be replaced and it will be drawn in through the joint at the focus ring on the lens, so a microfilter is a great idea
