SIGMA has been crafting lenses specifically designed to appeal to every type of photographer since the launch of SIGMA Global Vision back in 2012. Since then, SIGMA has been innovating the most standard of workhorse zooms to the apex of niche astrophotography gear. This year, SIGMA announced several new takes on old favorites, including the 24-70mm F2.8 DG DN II | Art — a reinvention of a classic complete with more bells and whistles than ever before.
