            The image quality differences most easily noticed between the 1.4x II and the 1.4x III are: The 1.4x III has less barrel distortion than the 1.4x II. This makes the center-of-the-frame details slightly smaller in a comparison. This difference will be most noticeable in the top crop shown in the ISO 12233 chart tool.Jan 31, 2011
