Unprecedented Image Quality: With Sony 70-200mm F2.8 GM OSS II, the picture quality is not compromised throughout full the zoom range. Two aspherical elements, one an XA (extreme aspherical) type, ensure high resolution throughout the image area. Two ED (extra-low dispersion) glass elements, two Super ED glass elements, and one ED aspherical element minimise chromatic aberration.
