This is a lightly used Sigma EX 50mm f/1.4 DG HSM for Nikon AF DSLR Cameras, in excellent working condition. This lens can deliver very sharp, richly-detailed, pro-level imaging with beautiful bokeh. Excellent imaging even wide-open. Very well-built, and with an outstanding optical formula and coatings. Comes as pictured with a 77mm UV Protector filter and both front & rear lens caps.
