Leica's Tri-Elmar-M 16-18-21mm f/4 ASPH covers three ultra-wide settings in one M lens, switched by click stop rather than zoomed. The design runs to ten elements in seven groups with aspherical surfaces, focusing to 0.5m and taking E67 filters on a non-rotating male thread. Because no M body has framelines this wide, it is offered as a set with the Universal Wide-Angle Finder M, which carries frames for 16, 18, 21, 24 and 28mm together with a spirit level and click-stopped parallax compensation.
