“Customers who register specific Leica products in the Leica Account/Owners Club portal will receive a 1-Year Leica Warranty Extension and a 3-Month Leica Fotographie International (LFI) Digital Subscription. This incentive applies to the registration of purchases of a new Leica M, SL (body or lens) or Q2 from a Leica Authorized Dealer. All products must be registered within three months of the original purchase. In a goodwill gesture, Leica Camera will offer the warranty extension and LFI subscription to all consumers who have purchased a qualifying product from October 1, 2019 through September 30, 2021, provided they register their product or activate the offers via the Leica Account/Owners Club by December 31, 2021.”
