  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.

• 

  Super ED Glass

  Nikon has also developed Super ED glass featuring even lower dispersion properties and extremely high performance in reducing the secondary spectrum, to minimize chromatic aberration even further, as well as other lens aberrations.

• 

  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.

• 

  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.

• 

  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.

• 

  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.

• 

  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.

• 

  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.

• 

  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.

• 

  A/M

  A/M stands for Auto-Priority Manual Mode. This mode also enables an easy transition from autofocus to manual during AF operation. However, mode switch sensitivity has been altered to reduce the possibility of sudden unintentional switching to manual focus while shooting.
