  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.

  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.

  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.

  Meso Amorphous Coat

  Meso Amorphous Coat* realizes the highest anti-reflection performance in NIKKOR history. Meso Amorphous Coat provides an effect superior to that of Nano Crystal Coat for diagonal incident light, and an effect equivalent or superior to ARNEO Coat for vertical incident light. With its superb performance, ghost and flare caused by incident light from various directions are noticeably reduced, delivering clear images even under harsh conditions.  *With this coating system, amorphous particles, that are even smaller than nano particles, are utilized to create even more gaps within the coating to form an ultra-fine mesoporous structure, attaining a lower refractive index. In addition, a higher-precision base coat is employed to further enhance the anti-reflection effect.

  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.

• 

  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.

• 

  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.
