The Contax 35-70mm f/3.5-5.6 T* Vario Sonnar is a standard zoom lens for the Contax 645 and Contax SLR family, offering a versatile mid-range focal length with the Carl Zeiss T* multi-coating. Designed as a walk-around zoom for general photography, it covers wide-angle to short telephoto in a single barrel.

At UK auction in late 2025, a copy of this Vario Sonnar achieved a hammer price of £170, which sets the only datapoint for what the lens is currently worth at saleroom level. With just a single recorded sale, today's market read is provisional, and clean examples with original caps and hood may sell for more in the retail channel than the wholesale auction figure suggests.
