Earlier Hasselblad C-type Zeiss Sonnar 150mm, same legendary optics as CF at potentially lower pricing for 500-series.
The Hasselblad C 150mm f/4 is a portrait telephoto prime for the Hasselblad V 6x6 system — the older C-series version with Compur shutter. Distinct from the later CF 150mm f/4 T* (id 2704) which has the improved F-type shutter and T* coating. Hasselblad V mount.
f/4 maximum aperture. 150mm focal length (Hasselblad V; approximately 84mm FF equivalent). C-series Compur shutter (older generation, without T* coating). Manual focus. Hasselblad V mount.
The C 150mm is the earlier generation — the C series uses the Compur shutter without the later F-type flash sync improvements of the CF series. Optically equivalent for non-flash work. An affordable entry into V-system portrait telephoto.
On the used market the Hasselblad C 150mm f/4 is an affordable V portrait telephoto. Condition checks: Compur shutter (check all speeds), front element. Hasselblad V mount — C series (older than CF, id 2704).
