We have been expecting Sigma to make an X mount announcement for a while now and the upcoming event on February 21st just might be the event. Sigma currently has 4 mirrorless APS-C lens designs that they could adapt to X mount so we could see any one of these lenses or all of them or something else entirely. I personally hope that it is something else entirely because I never really enjoyed these lenses on E-mount, but some photographers love Sigma.
