Lens Overview — Contax 210mm f/4 Zeiss Sonnar T*

The Contax 645 AF 210mm f/4 Zeiss Sonnar T* is a medium format telephoto prime lens built exclusively for the Contax 645 camera system. Designed as a true prime at 210mm, it carries the Sonnar optical formula under the Zeiss name, paired with the T* anti-reflective coating that Zeiss lenses are widely associated with. With a maximum aperture of f/4, this lens delivers a working balance between light gathering and physical size for a medium format telephoto.

It supports both autofocus and manual focus operation, giving shooters the flexibility to switch between focusing modes depending on the demands of the situation. The filter thread measures 77mm, a standard size that makes it straightforward to pair with common filter systems. Weighing in at 1,200g, this is a substantial piece of glass befitting its medium format telephoto designation.

Image stabilization is not present in this lens. The Contax 645 mount is a dedicated system mount, meaning this lens is purpose-built for Contax 645 bodies and is not natively compatible with other camera systems without adaptation. For photographers already invested in the Contax 645 ecosystem, this 210mm prime represents a focused telephoto option in the lineup.
