    • Versatile super-telephoto zoom lens
      Powerful super-telephoto zoom lens that’s perfect for sports and wildlife shooting offering constant maximum aperture and VR II Image Stabilization.

    • Nikon VR II (Vibration Reduction) Image Stabilization
      Vibration Reduction, engineered specifically for each VR NIKKOR lens, enables handheld shooting at up to 4 shutter speeds slower than would otherwise be possible, assuring dramatically sharper still images and video capture.

    • Nano Crystal Coat
      Further reduces ghosting and interior flare across a wide range of wavelengths for even greater image clarity.

    • 4 Extra-low Dispersion (ED) Elements
      Offers superior sharpness and color correction by effectively minimizing chromatic aberration, even at the widest aperture settings.

    • Three Focus Modes
      A/M mode joins the familiar M/A and M modes, enhancing AF control versatility with fast, secure switching between auto and manual focus to accommodate personal shooting techniques.

    • Internal Focus (IF)
      Provides fast and quiet autofocus without changing the length of the lens, retaining working distance throughout the focus range.

    • Exclusive Nikon Silent Wave Motor (SWM)
      Enables fast, accurate and quiet autofocus.

    • Nikon Super Integrated Coating (SIC)
      Enhances light transmission efficiency and offers superior color consistency and reduced flare.

    • Rugged Construction
      Featuring enhanced dust and moisture-resistance, magnesium die-cast barrel construction and a protective meniscus front lens.

    • Close Auto Focusing to 6.6 feet at all focal lengths
      Focus to 6.6 feet using AF or 6.4 feet using manual focus enabling striking image perspectives.

    • Rounded 9-Blade Diaphragm
      Renders more natural appearance of out-of-focus image areas.

    • Compatible with TC-14EII (AF/MF), TC-17EII (MF), TC-20EII (MF) and TC-20EIII (MF) Teleconverters.
