What exactly is purple fringing. Er what I mean is it a 'bug' with the sensor handling the dynamic range in a local transition or an actual chromatic feature of the lens. It is a bit confusing that aperture has an impact unless it has something to do with the size of the transition and the smaller aperture reduces the spread of the transition to a pinpoint but then why would the sensor handle this situation better? Is it because the transition is hitting fewer cells on the sensor or some other factor ?
