Does anyone have the 12-40 lens paired with the E-M5? Is it too big. I'm ready to pull the trigger on the camera and other than the 12-40 I'm not really satisfied with the available Olympus lenses; it just seems like it'll be too big. I'm thinking I should just go with the 12-50 kit and hope for the best with future options. I'm an old OM-1 and OM-2 owner and really love the look of the E-M5.
