That's not entirely true. Both Tamron and Tokina have pretty much nailed the EF protocols, and they don't normally have issues with newer bodies unless the lenses are from the early years of EOS. It's Sigma that continues to have problems with anything electronic (Ironic since their Sigma AF mount is actually a clone of EOS electrically). -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
