2018 marks the 50th anniversary of the International Leica Society (LHSA). To commemorate the occasion, Leica has produced a special anniversary edition of the APO-Summicron-M 50 f/2 ASPH. The lens has been designed to resemble the Summicron 50 f/2, which was introduced in 1954 together with the Leica M3. Though originally launched as a retractable lens, it was subsequently also available as a rigid version from 1956.

The contemporary APO-Summicron-M 50 f/2 ASPH. exploits fully the capabilities of modern digital camera systems in terms of contrast and resolution. With the Special Edition, this unparalleled imaging performance has been combined with the vintage look and feel of a 1950s Summicron. The lens body features a brass exterior with either a black paint or silver chrome finish. The era of early Summicron lenses is further referenced in the separate lens hood and lens cover, both of which are also made of brass, and finished to match the selected lens.

The Special Edition is limited to 500 units, comprising 300 black paint and 200 silver chrome models. The distance scale is engraved in red, while all other engravings are inlaid either in white (on the black paint models) or black (silver chrome models). The special-edition serial numbers are shown on the aperture ring, while the LHSA logo is inscribed (without inlay) on the bayonet ring, just above the ‘Made in Germany’ lettering. In addition to the warranty card, test certificate and user manual, the premium-quality packaging also contains a certificate of authenticity.

Leica Camera AG has collaborated with the LHSA on several special editions to date. The Society, which also publishes a quarterly magazine titled ‘Viewfinder’, is specifically dedicated to the exploration of Leica’s history and products. Previous LHSA special editions include a set comprising a classic MP of 1956 with a retro-style Summilux-M 50 f/1.4 ASPH.; a black-paint M6 TTL; and a Leica MP (released in 2003) with Leicavit, in a hammertone finish.
