Our most advance lens technology comes together in a compact, lightweight 70-200mm F4 telephoto zoom G Lens that delivers outstanding optical and AF performance as well as half-macro capability through the zoom range. | Excellent corner-to-corner resolution and contrast throughout the zoom ranger are achieved by combining AA (advance aspherical) and aspherical lens elements. Three ED (Extra-Low Dispersion) elements and one Super ED element suppress chromatic aberration and color bleeding fore revealing sharpness. Exquisite full-frame bokeh is enhanced by a circular 9-blade aperture mechanism and optimized spherical aberration. | Eye-opening close-up performance, being the first in its class to offer half-macro capability throughout the zoom range. | The FE 70-200mm F4 Macro G OSS II is fully compatible with Sony’s 1.4x and 2.0x teleconverters, in addition to increasing maximum focal length, the 2.0x teleconverter make it possible to shoot life-size 1:1 macro at all focal lengths for new creative potential. | Four of Sony’s original high-thrust XD linear motors work in conjunction with precision floating focus groups to achieve extremely fast, accurate focus drive.
