Here's the Bing translation of the relevent text, "But the date is TBD. It is said that even if it was released just a prototype of this specification is not always." "KQ-mount adapter was exhibited electrical contacts at all without focus, manual exposure metering only and rather narrow specification. No aperture ring K mount lenses, such as the DA lens （ ） of merits and against was equipped geared ring aperture mount adapter." "Venue DA 40 mm F2.8 Limited and DA the 60-250 mm F4 ED [IF] SDM with demo had been done. DA 40 mm F2.8 Limited 35 mm equivalent focal length 220 mm equivalent, DA the 60-250 mm F4 ED [IF] SDM is 1,375 mm equivalent. Ultra Telephoto angle can be obtained in small systems." I take that to mean it was a prototype explaining why it didn't yet have AE or AF contacts, and a liberal interpretation suggests it will have a "geared ring adapter" for K mount lenses, such as the DA lens" that have "no aperture ring". 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.
