What can you do when you get dust inside a lens. For the last little while I had noticed a spot on shots taken with my 17-85, and when I looked at it today I could see dust inside.
Any info would be much appreciated.

My 17-85 had a notable amount of dust in it when I sold it. Short of disassembling your lens there doesn't appear to be any reliable way of getting rid of it. Doesn't affect IQ so I wasn't overly concerned though it is irritating.

are you sure the dust you see on your pictures is not sensor dust?

Do a search on here for sensor cleaning... make sure you do your research before you go blasting at it with aerosol cans or such ;) A rocket blower (small thing you squeeze, not aerosol) works for me.

The dust in your lens is really not likely to be showing up on your pics, it's probably gonna be sensor dust :)
