What a difference a couple of years makes!
Two years ago, we were gearing up for PhotoPlus, just days after the announcement of the Sigma Global Vision at photokina 2012. We were preparing ourselves for discussions and briefings to explain the philosophy behind the three new lines being offered.
At that time, many photographers and technical editors were confused as to what Art, Sports, and Contemporary was meant to convey in a lens name. We spent a lot of time that fall explaining the way that Sigma is rethinking lenses and how this relates to the three new lens markings.
