Just had the opportunity to take my new G6 out and was disappointed to find that the auto focus is noticeably slower than my soon to be departed G3. Tried it with the Sigma 30mm and Panasonic 14mm. I thought it was all in my head so I put the same lenses on the G3 and suddenly I had the familiar instantaneous auto focus. The G6 is now on a par with my X100 on the new v2 firmware when it comes to auto focussing speeds. Anyone else noticed this? I gather this is the same sensor as the GH2 so maybe that's why? I'm quite disappointed.
