On the plus side the Pentax FF isn't coming out for awhile, so lots of time for Sigma to change their minds
Sigma and Tamron are going the quantity business.. if they dont sell K mount they just stop doing it..or they release lenses ( like Sigma ) that have more rotation ( lower priced lenses ).. for example Sigma have in the Art series the 30, 35 and 18-35 f1.8.. but they dont have the rest because are more "pro" oriented.. with the release of a FF, there will be some amount of people shooting Pentax at a pro level so they could release this lenses.. hopefully this can happen in the future. I'll love to have a Sigma 50mm Art.
