Zeiss Biogon T* ZM 1365-652-L 25mm
The symmetric 9-element Biogon design delivers virtually zero geometric distortion and high resolution across the full-frame image circle, aided by T* anti-reflective coatings. Its compact 260g all-metal build and precise manual focus ring make it an unobtrusive, durable tool for Leica M shooters. This lens is best for architectural and landscape photographers who demand edge-to-edge sharpness and distortion-free lines in a lightweight prime.
