I've got a D70s with AF-S 18-70mm 1:3.5-4.5G lens.
My lens seems to have something on it coz i'll get some unwanted spots and lines in my pictures. i've not been using it frequently so im not sure what's the cause.
i believe i need to go for servicing.
anyone could tell me where's the best place to go and how much it'll cost?
and im wondering how often will i need to service it?
