DESCRIPTION
Stepping MotorThe Nikon NIKKOR Z 20mm f/1.8 S Lens utilises 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.
Electromagnetic Diaphragm MechanismAn electromagnetic diaphragm mechanism built-in to the lens barrel of the Nikon Z 20mm f/1.8 S Lens provides highly accurate electronic diaphragm or aperture blade control when using auto exposure during continuous shooting. With conventional D/G type lenses, the diaphragm blades are operated by mechanical linkage levers.
ED (Extra-Low Dispersion) GlassAn optical glass developed by Nikon that is used with normal optical glass in telephoto lenses to obtain optimum correction of chromatic aberrations.
Nano Crystal CoatAn 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 LensA 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 LensA 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 CoatingNikon Super Integrated Coating is Nikon's term for its multilayer coating of the optical elements in NIKKOR lenses
