Has anybodoy gone to Tithes marketing for their Tamron lens to be cleaned before? (Tithes marketing is the distributor and also the company which guarantees Tamron lens in Singapore) How are their service?
Of course, I'm most particular especially since for AF zoom lens, there is a danger of the lens losing its precision in AF. Mine is a 28-200mm XR lens.
How about 3rd party shops like The Camera Workshop? What are your personal experiences?
