The FE 24-70mm F2.8 GM II is an updated "holy trinity" standard zoom, packing evolved optics and AF performance into a convenient, compact, lightweight zoom design that offers maximum mobility for both stills and movies. It is an ideal match for high-performance compact ? system bodies, and will cover a wide range of shooting situations. Excellent contrast at high spatial frequencies means superb resolution even at F2.8. Two high-precision XA (extreme aspherical) elements, two ED (Extra-low dispersion) glass elements, two Super ED glass elements, and a floating focus mechanism control chromatic aberration, astigmatism, distortion, and coma at all zoom and aperture settings. Nano AR Coating II subdues flare and ghosting for outstanding clarity. Exquisite F2.8 bokeh extends throughout the zoom range thanks to advanced optical design and a new 11-blade aperture unit. Bokeh is enhanced by precise control of spherical aberration during design and for each lens during manufacture. Two XA ele
