The XCD 21mm is an ultra wide-angle lens for the X System. Its extremely short focal length provides a 17mm full frame equivalent lens, making it perfect for landscape and architecture photography. The lens features a 32 cm close distance setting (1:10 image scale) and an aperture range between 4 and 32. The XCD 21mm also features full automatic focusing as well as instant manual focus. As part of the X System lens range, its lightweight and compact size perfectly complements the compact X1D body. Like the other XCD lenses, the XCD 21mm lens has an integral central shutter offering a wide range of shutter speeds and full flash synchronisation up to 1/2000th second.
