A superb lens that covers nearly
every professional wide-angle task.
Outstanding optical performance
comes from three Aspherical lens
elements, and (for the first time
ever in an EF wide-angle zoom
lens) two Ultra-low Dispersion
UD elements. Weather-resistant
construction, a rear gel filter
holder, close-focusing to 11 inches
(0.28m) and a circular diaphragm
are among its many highlights.
