This superbly crafted lens offers the long-range telephoto power you need to capture distant sports, wildlife, and landscape subjects. Built to the meticulous standards of our G series lenses, it boasts a bright, F2.8 aperture that lets you use faster shutter speeds, and an 8.1º angle of view that lets you zero-in on an area 1/36th the size of the image area of a 50mm lens. With a minimum focusing distance of just 2.0m/78.7", you can even use it for portraits and close-ups.

Contrast and resolution are unparalleled, and three ED (Extra-low Dispersion) glass lens elements are incorporated to thoroughly correct chromatic aberration.The lens is also equipped with a responsive SSM (Super Sonic wave Motor) autofocus drive system for precise,quiet focusing, as well as a focus hold button, an electronic focus range limiter, and two DMF (Direct Manual Focus) modes: one that lets you fine-tune the focus manually after autofocus has been achieved, and one that lets you adjust the focus manually anytime.
