Returning the lens is exactly what I intend to do... after I try it out on the *istDS this weekend. Not my intended use for this lens, but B & H customer service is closed on Saturdays and UPS/FedEx doesn't pick up on Sunday. It should give me enough info to see if I can live with its size and weight.
OTOH, now knowing that the SDM is prone to failure, perhaps all the more reason to stick with my so-far faultless <knock on wood> DA 16-45. I don't intend to spend this type of money on an manual focus lens for my K200D. - Pat On Sat, Aug 22, 2009 at 10:17 AM, Carlos Royo<carlos_r...@teleline.es> wrote: > I have a DA 50-135 which has developed exactly the same problem, namely: > screwdriver focusing works on an *ist DS, but SDM doesn't (on a K10D GP). > You should return that lens. > > Carlos -- 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.
