Sony Fe 70-300mm F4.5 - 5.6 G Oss Telephoto Zoom Lens Sony's longest reaching E-mount lens to date, the new Fe 70-300mm F4.5 - 5.6 G Oss telephoto zoom lens (model SEL70300G) features a state-of-the-art optical design including four aspherical glass elements, two Ed (Extra-low Dispersion) glass elements and Sony's Nano Ar coating, which all work together to effectively suppress spherical aberration, distortion, and chromatic aberration. This ensures beautiful high-resolution results for both still and video shooting. The new telephoto zoom lens also features class-leading close-up performance, with a minimum focusing distance of less than 3 feet (0.9m) and a maximum magnification of 0.31x, making it an ideal choice for tele-macro photography. This outstanding close-up performance also factors into the lens' excellent corner-to-corner sharpness.
