ZUIKO DIGITAL
ED 90-250mm F2.8

This powerful super-telephoto zoom lens with large-aperture (fixed F stop type) is equivalent to 180-500mm on a 35mm camera. Only fixed focal super-telephoto lens could have provided wide-open F2.8 shots in the past, however, this lens provides F2.8 shots in entire zoom area. Therefore, it can give the best framing at once even if you are in the restrained shooting spot. The best choice for the nature and sports photographer. Luxurious three ED lenses are used to give the highest image quality with optimal resolution and contrast.
