I have read several questions here regarding dust in a camera lens: should I be worried about getting dust, will it affect the image, and is it a problem. One answer suggested that "zoom lenses are prone to 'inhale' dust, simply by the act of zooming."
While the answers suggest that dust isn't a problem with regards to image quality, I am concerned about how to remove dust that is already in the lens, and how to reduce the amount of dust getting in. In my case I have a Tamron 18-270 zoom lens and recently while cleaning the lens I noticed a particularly noticable white spec on the inside of the outmost piece of glass. On closer examination I found a dozen specs of dust on the outside of the next to outermost surface, and four (including the most noticable spec) on the inside of the outermost. If zoom lenses can inhale dust so easily, is there a way to get them to exhale it? Is there some way I can get the dust out myself? I'm interested less from the perspective that my images will be compromised (although I would be interested in seeing a difference frame between dust and no-dust before I believe it truly has 0 effect) and more from a bit of OCD and not wanting to let the problem escalate.
