Leica Summilux-M 11668 28mm
Its 28mm f/1.4 aperture, single aspherical element, and 10-blade diaphragm combine to deliver extreme corner-to-corner sharpness with a creamy, shallow depth of field. The lens’s 280g all-metal construction and smooth manual focus ring make it a compact, durable travel companion that excels even in harsh lighting.
