Hi, I could do with some advice please on a used Canon EF-S 17-85mm f:4-5.6 IS USM lens which I purchased last week, the seller stated a little bit of dust was inside but now its here I would prefer to get it cleaned.
What would the approximate cost be to take it into an authorized UK Canon dealership, or would I be better to just remove the little inner ring and take out the 3 screws that hold the top glass in place and just blow it out and clean it with a micro fiber cloth? bearing in mind I have never done this before, I have seen a video and a piece of medical tape was used so the glass can be put back in the correct position.
Any help offered and definitely appreciated please.
Many thanks, Wayne.
