My 18-70 seems to have a gazillion specks of dust inside.. the front and rear look fine so it must be inside. Was wondering how much cleaning a lens at the service center will average.
if your images quality do not suffer from these gazillion specks
i'd suggest leaving it alone
I met a guy who ask me to remove dust on this type of lens.
At first, I told them that it does not affect the picture quality.
But the guy insist and even wants to prove it.
In the end, I cleaned his lens.
Maybe this lens should be stored upside down(lying on the mount) to avoid the front glass collecting dust.
