"Is the 24-70 f2.8 lens SDM only? Or does it also work with the old style cam driven AF as well as SDM? I assume it is SDM only but haven't found a review that says one way or the other."
Pentax has not produced any dual drive lenses since the first two SDM lenses--the 16-50 and 50-135. Joe -- 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.
