Contax 28-70mm f/3.5-4.5 Vario Sonnar T* MM C/Y Mount Lens {67}

Zeiss-designed 28-70mm standard zoom for C/Y mount shooters.

The Contax 28-70mm f/3.5-4.5 Vario Sonnar T* MM covers the most-used focal range in photography, wide enough for environmental work at 28mm, tight enough for head-and-shoulders portraits at 70mm, all in a single Zeiss-engineered barrel. The Vario Sonnar optical design, paired with Zeiss T* anti-reflection coating, gives this lens the contrast and color rendering that made Contax glass worth seeking out decades after production. The MM designation means it communicates aperture data to the camera body, so aperture-priority and program AE modes work as intended on compatible Contax/Yashica bodies.

The 67mm filter thread is a practical standard that makes polarizers and ND filters easy to source. Manual focus operation puts full control in your hands, which suits deliberate shooters who aren't chasing action. On a modern mirrorless body via a C/Y adapter, this lens pairs with on-sensor focus magnification and focus peaking, making the manual-only workflow entirely workable for still subjects. For the price of admission into Zeiss optics, this zoom is one of the more accessible entry points into the C/Y ecosystem.

Who It's For

Film photographers shooting Contax RTS or Aria bodies get the full MM functionality, aperture-priority metering works without workarounds. Street and travel photographers who want a single lens covering 28-70mm without swapping glass mid-shoot will find the focal range genuinely practical. Mirrorless adapters (Sony E, Fujifilm X, Micro Four Thirds) have made this lens attractive to digital shooters drawn to Zeiss T* rendering at a fraction of modern Zeiss pricing. Portrait photographers working at 70mm and stopped down will appreciate the T* coating's resistance to flare in mixed or backlit conditions.
