MINT Contax Carl Zeiss Vario-Sonnar 80-200mm f/4 MMJ MF Zoom Lens C/Y JAPAN

The Carl Zeiss Vario-Sonnar T* 80-200mm f/4 MMJ is a Japanese-manufactured Zeiss telephoto zoom lens for the Contax/Yashica mount system. Covering portrait to telephoto focal lengths with a constant f/4 aperture throughout the zoom range, it is one of the most capable zooms in the Contax CY lineup. The MMJ designation identifies it as a later Japan-made variant in the MM series. The f/4 maximum aperture remains constant across the full 80-200mm zoom range, eliminating the exposure shift that occurs when zooming with variable aperture lenses. This makes exposure management more predictable and consistent, particularly in manual or aperture-priority shooting modes. The Vario-Sonnar formula applies Zeiss's Sonnar-derived optical principles to a zoom design, maintaining the contrast and ren.
