I'm not sure how California Precision does dust control. I have had them repair several lenses, including an A*20mm F4 macro and a DA 21 Ltd. In all cases, the lenses came back clean inside and out.
Is there something special about the DA* 16-50 that would require, say, a class 100 clean room? --mark Margus Männik wrote: > >Hi there, > >first question against the conspiracy theory - does the authorized >service center have their own clean room? > >BR, Margus -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
