Sony E SEL20F28 20mm
Its 69-gram pancake design, protruding just 0.8 inches, pairs a bright f/2.8 aperture with a 20mm focal length (30mm equivalent) for a near-inconsequential footprint on APS-C cameras. The smooth, quiet autofocus and a 7.87-inch minimum focus distance enable discreet street captures and intimate close-ups without disturbing subjects. This lens is best for street photographers and travel shooters who prioritize pocketable, wide-angle versatility above all else.
