Carl Zeiss 150mm f/4 telephoto lens for Hasselblad medium format — compact build with characteristic Sonnar optical design.
Technical Details
The optical construction comprises six elements in four groups with a minimum focusing distance of 1.8 meters. The lens weighs 580 grams with a length of 103mm and a filter diameter of 67mm. The aperture ranges from f/4 to f/22 in full stops. The Sonnar 150 features Zeiss T* coating to reduce stray light and reflections. Two main variants exist: the early chrome model (1957-1970) and the later black model (1970-1988) with improved coating.
History & Development
Carl Zeiss introduced the Sonnar 150mm in 1957 as part of the first Hasselblad lens series. Production took place in Oberkochen under license from Victor Hasselblad AB. In 1970, the lens received the new T* multi-layer coating and the characteristic black finish. Production ended in 1988 with the discontinuation of Hasselblad V-System lenses by Zeiss. Approximately 45,000 units were produced in both variants.
Practical Use in Film
The Sonnar 150 is primarily used in portrait photography and for detail shots, as the 150mm focal length on medium format corresponds to a 90mm lens on 35mm film. Cinematographers appreciate its compact design and low weight compared to modern telephoto lenses. The characteristic Sonnar look with soft bokeh and moderate contrast is suitable for atmospheric shots. Sharpness peaks at f/8, while there is a slight softness at the widest aperture.
Comparison & Alternatives
The Sonnar 150 differs from the Hasselblad Planar 135mm due to its longer focal length and Sonnar construction with fewer lens elements. Modern alternatives like the Zeiss Makro-Planar 120mm CFE offer autofocus and better correction but do not achieve the compact form factor of the Sonnar. For digital Hasselblad systems, the HC 150mm f/3.2 is available, but it is significantly larger and heavier. Collectors prefer the early chrome model due to its lower production numbers and vintage look.
