  Short-Wavelength Refractive Lens

  SR is a high- and specialized-dispersion glass lens that refracts light with wavelengths shorter than that of blue. By controlling short-wavelength light, the lens is able to achieve highly precise chromatic aberration compensation so that the colors in your images are more accurately reproduced. It also allows for more flexible optical designs, which allows for compact, lighter lenses to be designed.

  ARNEO Coat

  An anti-reflective coating developed by Nikon and used in conjunction with Nano Crystal Coat to further reduce ghost and flare effects caused by incident light entering the lens vertically. This allows for the outstandingly clear capture of images even when a light source is located within the frame.

• 

  Stepping Motor

  NIKKOR Z lenses use a stepping motor for fast, accurate, smooth, quiet autofocus with reduced wobbling. This quiet drive system makes the lenses ideal for use when shooting video.

• 

  Fluorite Lens Element

  Fluorite (FL), a lightweight mono-crystal optical material, has excellent optical properties while reducing overall lens weight to improve balance and handling, especially useful in longer focal length lenses.

• 

  Fluorine Coat

  Photographers need gear that can withstand the elements. Nikon’s fluorine coat effectively repels dust, water droplets, grease or dirt, ensuring easy removal even when they adhere to the lens surface. Nikon’s fluorine coat endures a high frequency of lens surface wiping and its anti-reflective effect also contributes to the capture of clear images.

• 

  Electromagnetic Diaphragm Mechanism

  An electromagnetic diaphragm mechanism in the lens barrel provides highly accurate electronic diaphragm or aperture blade control when using auto exposure during continuous shooting.

• 

  ED (Extra-Low Dispersion) Glass

  An optical glass developed by Nikon that is used with normal optical glass in telephoto lenses to obtain optimum correction of chromatic aberrations.

• 

  Nano Crystal Coat

  An anti-reflective coating developed by Nikon that virtually eliminates internal lens element reflections across a wide range of wavelengths. Nano Crystal Coat solves ghost effects caused by red light and effectively reduces ghost and flare caused by light entering the lens diagonally.

• 

  Aspherical Lens

  A lens with a curved, non-spherical surface. Used to reduce aberrations and enable a more compact lens size. Aspherical lenses minimize coma and other types of lens aberrations, even when used at the widest aperture. They are particularly useful in correcting distortion in wide-angle lenses and help contribute to a lighter, more compact design by reducing the number of standard (spherical) elements necessary. Aspherical lens elements correct these distortions by continuously changing the refractive index from the center of the lens.

• 

  IF Lens

  A NIKKOR lens in which only the internal lens group shifts during focusing. Thus, IF NIKKORS do not change in size during AF operation, allowing for compact, lightweight lenses capable of closer focusing distances. These lenses will be designated with the abbreviation IF on the lens barrel.

• 

  Super Integrated Coating

  Nikon Super Integrated Coating is Nikon's term for its multilayer coating of the optical elements in NIKKOR lenses.

• 

  Vibration Reduction

  A Nikon in-lens technology that improves image stability by automatically compensating for camera shake. Lenses that offer VR will feature the abbreviation VR on the lens barrel.
