Excellent Image Quality. Despite its wide 90° angle of view, this lens offers very low distortion and excellent image quality across the frame. Its 1.8-ft. minimum focusing distance allows you to take exaggerated perspective shots, and its ten-blade curved aperture makes for smooth out-of-focus highlights. Its flare control and lack of geometric distortion provides useful accuracy for architectural, landscape, and product photography.

High-Quality Build. An all-metal lens housing gives the ZM 21mm f/2.8 Biogon a premium feel. Its manual focus ring offers precision focus adjustment and excellent speed.
