This powerful super-telephoto zoom lens with a large-aperture is equivalent to 180-500mm on a 35mm camera. Only fixed focal super-telephoto lenses provided wide-open F2.8 shots in the past. However, this lens provides F2.8 shots throughout the entire zoom range. Therefore, it can give the best framing at once even if you are in a restrained shooting spot. The best choice for nature and sports photographers. Three high quality ED lenses are used to give the best image quality with optimal resolution and contrast.
