Description — Contax 45-90mm f/4.5 Zeiss Vario Sonnar T*
The Contax 645 45-90mm f/4.5 Zeiss Vario Sonnar T* is a medium format zoom lens built specifically for the Contax 645 camera system. Its 45–90mm focal length range spans a practical standard zoom spread, making it a flexible option for photographers working across varied subject matter and distances. The lens maintains a maximum aperture of f/4.5 throughout its zoom range, ensuring consistent light handling from wide to telephoto.
Focusing is handled via both autofocus and manual focus modes, providing adaptability for different workflows. The 95mm filter thread accepts a broad range of filter accessories, though photographers should plan accordingly given the larger-than-average diameter. Weighing in at 1,200g, the lens has a substantial physical presence that reflects the demands of medium format optical construction.
There is no image stabilization, so a steady hand or appropriate support is advisable when shooting handheld. This lens is purpose-built for the Contax 645 mount and is not directly interchangeable with other systems.
