Leica Summicron-M 28mm f/2
The f/2 aperture and single aspherical element deliver high contrast and edge-to-edge sharpness across full-frame Leica M sensors, with a 0.4m minimum focus enabling detailed close-up compositions. Its 275g all-metal brass build and dual-curve manual focus mechanism provide a durable, precise tactile experience despite the absence of weather sealing. Environmental portrait and street photographers seeking a fast wide-angle lens with 10-blade diaphragm bokeh will find it most valuable, though its landscape performance scores lowest.
