Quote: I'm aware that Sigma has continued to sit on the sidelines with no stated intention of returning to k-mount land any time soon. I don't know that Sigma wouldn't agree to, say, a 10,000 piece run of 50 Art guts to ship to Pentax Vietnam for build-up into this lens. In fact, this seems pretty plausible, as what does Sigma have to lose save for a dent in the amount of 50 Art lenses they could sell in their own wrapper for a given amount of time in return for an agreed to sale of parts. Plus it might give them an idea of how well their sort of lenses sell in k-mount land without any real skin in the game.
Time will tell I guess.
I don't see it that way at all. Pentax is still designing lenses. Correction, look at the Pentax DFA 70-200, Pentax is still designing better lenses than Sigma does.Claiming Pentax is thinking of using rebadged Sigma's sounds more like Sigma guerrilla marketing than a valid comment. When they needed a few lenses to fill out their line up in a hurry, Pentax went to Tamron and I speculate part of that is their relationship with Jun Hirakawa. There is no indication anywhere of Pentax dealing with the mount reverse engineering Sigma corporation. That's a complete fabrication as far as I can tell.
Is the Pentax 1.4 going to be better than the Sigma 50 1.4 you ask? Well, is the DFA 70-200 better than the Sigma 70-200? There are precedents here.
Everyone wants to believe corporations like Sigma can do just as good for cheaper, and that's understandable, but probably not very realistic.
