The Nikon AF-S NIKKOR 80-400mm f/4.5-5.6G ED VR Lens is a versatile telephoto zoom lens that is compatible with both FX and DX-sized image sensors. This lens features an extensive zoom range of 80-400mm (DX equivalent: 120-600mm) that encompasses both portrait and long-reaching telephoto focal lengths to suit work with a variety of subjects. Capture portraits with softly blurred backgrounds and get close-up telephoto shots of faraway subjects with or without a tripod.The lens construction integrates one super ED (extra-low dispersion) and four ED glass elements to help minimize chromatic aberrations throughout the zoom range and contribute to higher image sharpness, clarity, and color fidelity. The Nano Crystal Coat reduces surface reflections, helping to prevent lens flare and ghosting for greater contrast and light transmission.Built-in Vibration Reduction image stabilization compensates for the effects of camera shake up to the equivalent of four shutter speed steps. A dedicated VR setting for tripods is available for producing the sharpest imagery possible without countering the effects of the image stabilization system.
