The Hasselblad XCD 45P 45mm f4s focal length is equivalent to about 35mm in a full-frame system, so this is a sort of wide-normal lens for your Hasselblad X-series digital camera. Even better, its impressively small: about the same size as the classic 80mm f2.8 C Planar, but lighter, and with full autofocus capability. A nice everyday lens with excellent image quality, in near-new condition. Includes box and leather pouch.
