Apparently word has spread to Olympus about the slow focusing speed of the E-P1, and they’ve released a firmware to makes things a bit snappier with both kit lenses. Initial reports indicate 40%-50% faster focusing!
Instructions for updating firmware using the Olympus Master 2 software that came with your E-P1 can be found here: http://www.olympus.co.jp/en/support/imsg/digicamera/qa/contents/03b/ssoftware10.cfm
