Today I took my son to a local pumpkin patch and it was really dusty.
by the end of the day I noticed my lens was not as smooth when I
zoomed in/out.

When I got home I cleaned the lens and body w/ my rocket blower
but not I'm noticing when i zoom in/out a grind noise like dust
inside but it is very minor.

Does anyone have any advice on what steps should be done to
remedy the issue?

Try twisting it stop to stop rapidly a few times to let it breath, if that doesn't help its off to Canon.


There is a fine line between "hobby" and "obsession"

Great, that is what I was just doing before I saw your message
and it is not present at the moment.
