Contax 100mm f/2 Planar T* C/Y Mount Lens Review

The Contax 100mm f/2 Planar T* is a classic manual focus prime lens built for the Contax/Yashica mount system. Known for its Zeiss optical formula and T* anti-reflective coating, this lens delivers the kind of rendering that has made Contax glass legendary among film shooters and vintage lens enthusiasts. The fast f/2 maximum aperture and smooth bokeh make it well suited for portraiture and low-light work, while the build quality reflects the premium craftsmanship of the Contax era.

This particular example is listed in excellent used condition from KEH, a reputable dealer in pre-owned photo equipment. At 67mm filter size and compact dimensions for a fast medium telephoto, it adapts easily to modern mirrorless bodies, though shooters will need the appropriate C/Y to camera mount adapter. The manual focus operation and lack of electronic communication mean this lens rewards patience and deliberate technique, fitting naturally into workflows that prioritize character and optical quality over autofocus convenience.
