Overview

The Leica Elmarit-M 21mm f/2.8 ASPH is a compact, practical ultrawide lens praised for its sharpness, low distortion, and smooth handling. Its f/2.8 aperture balances speed and portability, making it ideal for architecture, landscape, and street photography. Weaknesses include an 8-blade aperture producing pedestrian sunstars and a maximum aperture of f/16. It suits photographers comfortable with extreme wide angles; those preferring narrower fields may find it overwhelming.
