Yashica's affordable C/Y tele zoom — the ML 70-210mm f/4, multi-coated manual-focus glass for the C/Y mount.
The Yashica ML 70-210mm f/4 was a telephoto zoom of Yashica's ML line for the Contax/Yashica mount, sharing the C/Y bayonet with Contax Zeiss lenses. It offered a native telephoto zoom for the mount at a lower cost.
This is a manual-focus C/Y-mount zoom spanning 70-210mm with a constant maximum aperture of f/4. It fits the same bodies as Contax Zeiss glass and belongs to Yashica's ML series. Other optical figures are omitted where they cannot be verified.
The 70-210mm range suits portraits, travel telephoto framing and some sport and wildlife, giving reach and compression with the flexibility to reframe without switching lenses. It is a practical telephoto zoom for C/Y bodies.
Used copies are affordable as a budget telephoto zoom for the mount. Check the zoom and focus for smooth travel, look for internal haze, fungus and coating wear, and confirm clean aperture blades. It adapts to mirrorless with a C/Y adapter.
