NIKKOR Technology
Aspherical lens
Aspherical lens elements are particularly useful for correcting distortion and spherical
aberration. Because a single aspherical lens element provides a compensation eect
equivalent to that of several spherical lenses, a compact and light design can be
achieved.
For the NIKKOR Z 58mm f/0.95 S Noct, a larger-diameter, ground aspherical lens is
utilized. Besides providing uniformly precise lens surface, via the adoption of glass
material with a high refractive index that was previously considered dicult to employ
for molded-glass aspherical lenses, the ground aspherical lens accurately compensates
various lens aberrations with its outstanding aberration correction capability.
Optical technologies
ARNEO Coat
In addition to the proven Nano Crystal Coat, the newly developed ARNEO Coat anti-
reflection coating system is incorporated in some S-Line lenses. This advanced system
delivers an equivalent or superior anti-reflection eect to that of Nano Crystal Coat for
incident light reaching the lens surface from a vertical direction. Utilized in combination
with Nano Crystal Coat, ARNEO Coat enables the capture of clear and crisp images
with minimal ghost and flare eects even when a light source is located within the
frame.
Thanks to Nikon’s original thin-layer manufacturing technology with its optimized
algorithm, reflectance that closely approaches design values can be attained for every
lens with consistent quality due to high-density, uniform coating layer thickness, realizing
ultra-low reflectance stably over the entire visible light range.

ED (Extra-low Dispersion) glass
Nikon was the world’s first camera maker to develop ED (Extra-low Dispersion) glass that
could minimize prism-caused color dispersion. Color fringing caused by dierences in
focal length is eectively minimized.
NIKKOR Technology
Fluorine coat
Nikon’s fluorine coat eciently repels dust, water droplets, grease or dirt, ensuring
easy removal even when they adhere to the lens surface. Thanks to Nikon’s original
technology, it delivers higher durability and is more peel-resistant. Its anti-reflective eect
also contributes to the capture of clear images.
Nikon Super Integrated Coating
Nikon’s exclusive multilayer lens coating applied to all current lenses in the NIKKOR lineup
provides high transmittance over a wider wavelength range. Even for zoom lenses with
a large number of glass elements, this coating system eectively reduces the ghost and
flare eects that are likely to occur in backlit situations, helping you achieve high-contrast
images with rich gradation. With outstanding color balance and reproduction capability,
superb optical performance is delivered even in special applications including infrared
photography.
Focus breathing reduction in movie recording
Focus breathing is a phenomenon that shifts the angle of view when adjusting focus.
NIKKOR Z lens reduces this defect by carefully considering the optical system, ensuring
smooth movie expression with minimal shift of angle of view.
HRI (High Refractive Index) lens
With a refractive index of more than 2.0, one HRI lens can oer eects equivalent
to those obtained with several normal glass elements and can compensate for both
field curvature and spherical aberration. Therefore, HRI lenses achieve great optical
performance in an even more compact body.
Nano Crystal Coat
Nano Crystal Coat is an antireflective coating that employs an extra-low refractive index
coating featuring ultra-fine, nano-sized crystal particles. This coating eectively reduces
ghost and flare eects caused by red light and light entering the lens diagonally,
resulting in clearer images.
Aspherical ED glass
Using ED (Extra-low Dispersion) glass that successfully minimizes color fringing as a
material, this type of lens features non-spherical surfaces on one or both sides of the
glass. It provides superior rendering capability by maximizing the advantages of both
ED glass and an aspherical lens – eectively correcting various lens aberrations such
as lateral chromatic aberration, coma flare at the periphery, as well as distortion and
spherical aberration.
