Overview

The Leica Tri-Elmar-M 28-35-50mm f/4 Asph (MATE) offers three useful focal lengths in a compact unit, providing the convenience of a zoom with the discipline of primes. Optically, it delivers good sharpness but suffers from flare, especially at 50mm due to a shallow hood. Barrel distortion is noticeable at 28mm and 35mm. Build quality is high, though the lens is complex and expensive to manufacture. It suits Leica M photographers who value versatility and are willing to manage flare and distortion.
