Frogfish, I see no disagreement here. Where I disagree is the OP's inference that Pentaxians are too cheap and/or uninformed and/or unsophisticated to choose Sigma lenses. Pentax glass is superb, and it ain't cheap in price, or in quality of construction, or in quality of output.
Finally, I should say that I will not respond anymore. People will buy whatever lenses they choose for a myriad of reasons. I have been using Pentax lenses and cameras since 1972. My first choice for glass will always be Pentax. I have yet to be disappointed (and that includes DA* lenses). And that does not make me stupid, cheap, or ignorant.
