It's common for zoom lens to have dust in them.
Each time you zoom air/dust gets sucked into it.
If it doesn't affect your images save the time and money, and live with it.
Unless its a very serious case.
You may want to send it for servicing but after some time dust will get into it again.
Imagine how many times you have to go through that process in a year.
yep..but its not advisable to recalibrate your lens too much, probably once in two years.
the solution to this problem is to buy lens with internal zooming, and focussing:angel:
