Yashica's affordable C/Y telephoto — the ML 200mm f/4, multi-coated manual-focus glass for the C/Y mount.
The Yashica ML 200mm f/4 was a telephoto prime of Yashica's ML line for the Contax/Yashica mount, sharing the C/Y bayonet with Contax Zeiss lenses. It offered a native telephoto for the mount at a lower cost.
This is a manual-focus C/Y-mount lens with a 200mm focal length and a maximum aperture of f/4. It fits the same bodies as Contax Zeiss glass and belongs to Yashica's better-coated ML series. Other optical figures are omitted where they cannot be verified.
At 200mm f/4 the lens suits portraits at distance, travel telephoto framing and general reach, with useful compression in a manageable size for handheld use. It is a practical telephoto for C/Y bodies.
Used copies are affordable as a budget telephoto for the mount. Look for internal haze, fungus and coating wear, confirm smooth focus and clean aperture blades, and check the front element. It adapts to mirrorless with a C/Y adapter.
