Contax 28-85mm
A manual focus zoom lens with Vario-Sonnar optics and an f/3.3-4 aperture, built for the Contax/Yashica C/Y mount system.
Overview
The Contax 28-85mm is a manual focus zoom in the Carl Zeiss Vario-Sonnar line, made for the Contax/Yashica C/Y (MM) mount. It covers a full-frame image circle and carries T* anti-reflective coating. Users praise its microcontrast, its bokeh and a "3D pop" in the images. It is big and solidly built, and collectors still go looking for it.

Design
The optical formula is the Carl Zeiss Vario-Sonnar, with T* multi-coating to cut flare and improve contrast. It fits the Contax/Yashica MM mount and includes a built-in lens hood and genuine Contax filter. The design puts optical quality ahead of compactness, so the lens is large and heavy. Manual focus is smooth.
Context
The Contax 28-85mm f/3.3-4 was one of the high-end manual focus zooms that went with the Contax RTS series cameras. It often gets mentioned next to other C/Y mount lenses like the 28mm f/2.8, 50mm f/1.4 and 85mm f/2.8 as part of a premium lens set. Production years are unconfirmed, but it is associated with the 1970s era of Contax/Zeiss lens development and is regarded as one of the finest optical systems of its time.
Market
The lens sold for $450.00 in a recent private transaction (Fred Miranda forum). Earlier UK listings from 2010-2013 asked £399 for mint examples. Repair waits of 3+ months have been noted for similar Contax lenses that need service.
