Seems Sigma announced this week that they decided to completely stop producing Pentax mount lenses during the fall. Instead, it plans to focus more on developing and supporting mirrorless systems, in which they see the future. To which I say さようなら＆良いダンス (goodbye & good riddance if Google translator is correct). Never liked you anyway. I only have one Sigma lens and rarely use it because the Pentax glass is far superior. Maybe now Pentax will get off it's duff and expand the Star Series.
