Specification :
Presenting an ultra-wide field of view, the XCD 21mm f/4 is a 17mm-equivalent wide-angle prime designed for Hasselblad's mirrorless medium format XCD system. Well suited for landscape, interior, and architectural photography, this lens is also characterized by its close minimum focusing distance of 1' for creative close-up imaging. Matching the sophistication of the system, this lens features a pair of aspherical elements in its optical design, which helps to reduce spherical aberrations and distortion in order to realize high sharpness and accurate rendering. Like other XCD lenses, the 21mm f/4 has an integrated Central Lens Shutter that is capable of shutter speeds up to 1/2000 sec with flash sync at all speeds, and its internal autofocus design can be manually overridden for precise manual focusing control.
