Zeiss's constant-aperture Contax tele zoom — the Vario-Sonnar T* 80-200mm f/4, manual-focus glass for the C/Y mount.
The Zeiss Vario-Sonnar T* 80-200mm f/4 was a telephoto zoom for the Contax/Yashica mount, offered from the mid-1980s with a constant f/4 aperture across the range. The Vario-Sonnar name marks it as a Zeiss zoom design.
This is a manual-focus C/Y-mount zoom spanning 80-200mm with a constant maximum aperture of f/4. The fixed aperture kept exposure consistent while zooming through the telephoto range. Additional figures are omitted where they cannot be verified.
The 80-200mm range suits portraits, travel telephoto work and some sport and wildlife, offering reach and compression with the convenience of a single lens. The constant f/4 aperture supports steady exposure across the zoom.
Used copies provide a versatile Contax telephoto zoom at reasonable prices. Check the zoom and focus for smooth, even travel, look for internal haze, fungus and coating wear, and confirm clean aperture blades. It adapts to mirrorless with a C/Y adapter.
