Description — Contax 50mm f/1.4 MM
The Contax 50mm f/1.4 MM is a manual focus prime lens designed for the Contax/Yashica mount system. With a 50mm focal length in the standard range and a wide f/1.4 maximum aperture, it offers genuine versatility across portrait, street, and available-light shooting. The lens covers a full frame image circle, making it compatible with full frame bodies both natively and via adapter.
Weighing just 320g, it remains easy to handle over extended shooting sessions. The 55mm filter thread accepts a broad range of commonly available screw-in filters. There is no image stabilization and no autofocus — this is a deliberate, manual-only lens suited to photographers who value direct, tactile control.
Whether mounted on a vintage Contax/Yashica SLR body or adapted to a modern mirrorless camera, the 50mm f/1.4 MM delivers a classic standard prime experience built around that fast, expressive maximum aperture.
