    All lenses have dust. Older lenses may have more dust. At your level of dust, don't worry about it. It will have no issue for image quality. It will have no issues for your sensor.

    I have used n compressed air (the type you clean electronics with) from a can and forced the air, the best I could into the lens. First I take off anything easy to remove to expose any gaps as much as possible. After blowing the air on these gaps around the lens/glass, etc., I have been able to move some dust inside the lens. At the end of the process, I am sure the dust was still in the lens but I could not see as much of it so I considered it a success.

    Did this change my photos any... No. But it made me feel better...

    Thinking a little more, in case someone is going to try this at home, I also used a vacuum cleaner to draw air (creating a low pressure on one side of the lens) while blowing the compressed air canister on the other side of the lens. The goal was to create enough pressure difference across the lens to move some air through the lens. I operated the focusing and aperture rings with all of this going on. Again, I am not sure if I moved the dust out of the lens or just moved it around within the lens but I was able to reduce the amount of dust I could see on the lens elements.
