Notice Regarding Lenses with Altered Serial Numbers
Tamron products with erased or altered laser etched serial number have been found in the USA, Europe, China and elsewhere. These products had no or forged warranty cards.
Tamron cannot offer any warranty for products without a genuine warranty card, such as the ones noted above. In this case, all repairs are subject to charges.
Interchangeable lenses are precision optical products and defects or malfunctions may occur due to inadequate handling. Products with erased or altered serial numbers are exposed to vibrations when the original markings are scraped off. Tamron cannot guarantee the quality of such products.
