The Leica Summilux-M 50mm f/1.4 Version 2 (factory code 11114) employs a Double Gauss optical design with 7 elements in 5 groups. Introduced in 1992 as the successor to the 11860/11870 series, this silver chrome variant features a 43mm E43 filter thread and revised mechanics while retaining the classic high-speed formula. Total production reached 43,505 units before discontinuation in 2006, making it the final Summilux-M 50mm before the aspherical redesign.
