The Contax 180mm f/2.8 Sonnar T* is a medium telephoto prime in the Contax/Yashica bayonet system, built around the classic Sonnar optical concept and carrying the multi-coated T* treatment. It was aimed at portrait, sports and available-light work on 35mm SLRs, offering a fast aperture in a focal length favoured for compressed perspective.

At UK auction, hammer prices for this lens have been modest: recent results sit at £162 (October 2022) and £188 (March 2023), with an older 2006 sale at £300 marking the high end of the recorded data. The median hammer is around £188, and as of today in 2026 clean, fungus-free copies are what the market will pay for — these are wholesale saleroom figures rather than dealer retail, so a tidy example is typically worth a little more when bought from a shop. Buyers asking what a 180mm f/2.8 Sonnar T* sells for should expect most honest examples to trade in the mid-to-high £100s at the hammer.
