This updated classic mid-range telephoto lens delivers incredibly sharp images and its fast f/ 1.4 aperture ensures a bright viewfinder image as well as beautiful background blur. Well suited for portraits, general purpose and low light work. Use of Nano Crystal Coat further reduces ghosting and interior flare across a wide range of wavelengths for even greater image clarity. Focus distance indicator is 3 feet to infinity. Note that because this lens uses the nikon internal focusing system, focal length decreases as the focus distance shortens
