Because each nation within the EU implemented its own law on the basis of a EU directive, there is no uniform result within the EU in terms of warranty. In the United Kingdom consumers have a legal of warranty of 24 months.  A fault which becomes apparent within six months of the delivery of the goods is to be presumed to have existed at the time of delivery. This means that the consumer has a maximum of six months to establish that the goods do not conform to the contract. Further, the burden of proof is on the buyer.

We decided to keep our one year manufacturer warranty even after 2002. As of 01.01.2008 the 12 month European guarantee card (see sample) has replaced the international guarantee card, in order to meet the requirements of the linguistic diversity in Europe.  The card is included in each Tamron lens bought from an authorized dealer.
