Used Leica 50mm f/1 NOCTILUX-M Standard Manual Focus Lens with 6-bit lens identification code - for M & Digital M Systems

The NOCTILUX-M is the only f/1 lens for 35 mm photography manufactured in series by Leica. Because of this extraordinary optical performance it is eminently suited not only for photo-graphy at twilight, but also for night photography without flash - the light of a single candle is already sufficient. It produces outstanding contrast rendition, so that barely noticeable color differences are faithfully separated and the finest structures of the subject are resolved accurately, even under extremely unfavorable light conditions. The optical computation of this super-fast lens approaches the limits of what is physically possible. The NOCTILUX-M gives LEICA-M photography capabilities that are beyond the reach of other outfits.
