Take it back to the dealer and they will handle it for you. Here is an extract from my interview last year with the head of Zeiss Sports Optics UK and their official repairer:
Troubador: If a customer finds they have a problem with their Zeiss sports optics instrument, should they contact you or should they contact the dealer?
Luke: Please allow me to answer that. In all cases, whether the bino is new or was bought some time ago or was bought second-hand, we recommend the customer contacts the supplying dealer, or if this is not possible, any other conveniently located dealer. Our dealers and their locations can be found on our website by using the dealer locator. We cover the costs for dealers to provide this service, so they will receive the instrument, pack it up and send it to Gary for attention, and all with no charge to the customer. Their point of contact will remain the dealer and Gary will inform the dealer when the instrument is received and when it is on its way back. Having said that there is absolutely no reason why the customer cannot package the bino up and send it to Gary at East Coast Binocular Repairs, but most people find it convenient to leave that to the dealer, who, as I mentioned before, provides this service free of charge and does not add any ‘margin’ to the cost of a chargeable repair. Sometimes the cause for concern can be addressed simply by advice and guidance from the dealer.
