ZEISS guarantees for a period of 2 years from the date of purchase that the purchased lens is free from defects in material and workmanship. An extended warranty for one additional year is available by registering the product within 4-weeks of the date of purchase at the ZEISS product registration. The ZEISS manufacturer warranty applies in addition to your legal right to claim warranty towards the seller. This warranty is not transferable. (Certain regions may permit statutory warranty claims against your dealer that go beyond the terms stated in our manufacturer’s warranty. In such cases, please consult your dealer.) During the period of manufacturer's warranty, defects will be removed free of charge either by repair or replacement at the discretion of ZEISS. Claims under warranty shall not apply if the defect is attributable to improper treatment, including any interference with the product by unauthorized workshops or persons. The ZEISS manufacturer warranty is separated into several regions. The ZEISS warranty is only available in the region where the country you have purchased the lens belongs to. You can find the ZEISS warranty seal on the packaging of each lens. The quality seal is an identifier to which warranty area your product belongs. The country where you have purchased the lens decides which quality seal is valid. To make use of the ZEISS warranty please choose below the country where you have purchased the lens:
