This powerful super-telephoto zoom lens has a large-aperture (fixed F stop type) and is is equivalent to 180-500mm focal lenth on a 35mm camera. Only fixed focal super-telephoto lens could have provided wide-open f/2.8 shots in the past, however, this lens provides f/2.8 shots through the entire zoom range making it a best choice for the nature and sports photographer. Three ED lenses are used to give the highest image quality with optimal resolution and contrast.
