Thanks for the suggestions. I started out in "A." The lens doesn't transmit information in any setting.
I've cleaned the mounts on both the lens and body - to no avail. The body continues to work well with other lenses. What would disassembly fix entail? Larry in Dallas -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
