Sigma CEO Kazuto Yamaki has unveiled the company’s strategy for lenses. He stated that the priority now is the release of new DN family models. Recall that the Sigma DN is used for lenses designed for mirrorless cameras.
Yamaki said that the release of full-frame models remains the priority (they can be distinguished by the DG DN designation), but the company also realizes the need to expand the range of lenses for APS-C and Micro Four Thirds cameras. For such Sigma lenses, the DC DN designation is used.
