Anytime the lenses leave the house , when I finish for day , I check and clean filters and use a baby vacuum [ runs off 2 AA batteries- used to clean keyboards ] and do lenses /camera .

On the zoom lenses slowly extend to max , then push to shortest position . This can force out dust , pollen - etc .

Good tip.

However, my problem was, that the grain came in during the day while I was shooting.
