Well, that certainly kills off some entertaining speculation. The kindest thing I can say about Sigma's press release is that it was careless. Somebody in Sigma PR needs their arse kicked from here to Poughkeepsie. They unambiguously touted the virtues of the OS when announcing this lens for Pentax and Nikon, despite their own compatibility chart showing that the lens lacks its raison d'etre in these mounts. regards, Anthony "Of what use is lens and light to those who lack in mind and sight" (Anon) -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
