Contax 85mm f/2.8 Sonnar T* C/Y Mount Lens Review

The Contax 85mm f/2.8 Sonnar T* is a classic manual-focus portrait lens originally designed for Contax/Yashica mount film cameras. With Zeiss T* multi-coating and the traditional Sonnar optical formula, it delivers smooth rendering and good contrast in a compact, lightweight package. This particular listing from KEH offers used examples in various condition grades, making it an accessible entry point for shooters looking to adapt vintage glass to modern mirrorless bodies or use it on original film equipment.

At 85mm, it sits squarely in portrait territory, offering flattering perspective and a relatively wide f/2.8 maximum aperture. The Sonnar design is known for pleasant out-of-focus rendering, though not as creamy as faster Zeiss 85mm options. Adapting to Sony E, Canon RF, or Nikon Z mounts is straightforward, and manual focus is manageable with focus peaking. For film shooters or those building a vintage lens collection, it represents a more affordable alternative to the faster and pricier Contax Planar 85mm f/1.4.
