Overview

The Carl Zeiss Biogon T* 2,8/28 ZM is a well-regarded wide-angle lens for Leica M-mount, praised for its punchy, high-contrast rendering and low distortion. Optically, it outperforms the Leica Elmarit-M 28mm f/2.8 ASPH at half the price, though it is slightly larger and blocks more of the viewfinder. Weaknesses include noticeable vignetting at f/2.8 and field curvature causing soft corners at wider apertures. Build is all-metal, but the lens hood is sold separately and the lens may suffer from 'Zeiss wobble'. It suits photographers seeking a classic, contrasty look for travel, landscape, or street photography.
