The Distagon T* 21mm f/2.8 wide-angle lens is the most advanced version of the legendary Distagon (a high performance lens with close focus capabilities, first introduced in 1961). This lens is a recalculation of the original design for use with modern SLRs and DSLRs using either full-frame or smaller sensors. The close-focus capability increases the versitality of this lens, providing a wider perspective than the usual macro focal lengths.
