The overwhelming optical performance achieved
with the new Nikon Z mount
The newly adopted Nikon Z mount system features completely
new specifications such as a large inner diameter of 55 mm
and a short flange focal distance of 16 mm that permit
sucient light to be received even in the peripheral areas of
an image sensor. These specifications realize much higher
flexibility in lens design that enables the pursuit of new-
dimensional optical performance. As a result, the development
of incomparable, extremely high-performance lenses that were
conventionally dicult to produce is made possible.
The evolution of imaging devices with a higher pixel count,
higher frame rate and higher dynamic range is continuously
proceeding and “reality” is increasingly demanded for
images. In such a situation, this new mount was developed
to be compatible with the high-speed, large-capacity
communication of highly precise information that is essential
for enhancing the quality of expression as an imaging system.
Minutely detailed communication of diversified lens data
between the camera body and lens contributes to remarkably
advanced AF control with outstanding accuracy.
While greatly expanding the range of image expression, the
new-generation mirrorless
camera system featuring
the Nikon Z mount provides
remarkable potential and
possibilities to keep pace with
advancements in the imaging
technologies of today and the
future.
Nikon’s optical design technologies integrate
tradition with the latest breakthroughs
For over a century, Nikon has investigated how to express
three-dimensional space within two-dimensional images and
continuously explored in diverse directions. The results are
precise imaging performance on the focal plane ensured by
eective compensation for various lens aberrations that cause
bleeding, distortion and unclear images, and beautiful bokeh
characteristics enabled with the pursuit of optical performance
for both focused and defocused areas. To surpass the
performance of conventional versatile lenses, the new NIKKOR
Z lenses will enable active investigation of new possibilities
integrating traditional optical technologies consecutively
inherited from the NIKKOR concept with the dynamism of the
constantly advancing technologies.
The ground aspherical lens that is employed in the highest-
class model, Noct, is one of the results of these explorations.
Guaranteed grinding precision that was formerly an issue in
the mass production of large-diameter aspherical lenses was
attained through advancement of processing techniques,
realizing consistent surface accuracy. Also, in addition to Nano
Crystal Coat with its proven high tolerance for incident light
from a diagonal direction as well as a vertical direction, a
newly developed anti-reflective coating, ARNEO Coat, that
is more eective for incident light from a vertical direction
specifically, is adopted. Utilizing both of these coating systems,
ghost and flare are radically reduced for incident light from
any direction. Thus, Nikon’s optical design technologies
integrating tradition with the latest breakthroughs will further
enhance the optical performance of NIKKOR lenses.
S-Line lenses deliver the richest image
experience with elaborate optical performance
For the S-Line series of the NIKKOR Z lenses, a much higher
level of standards of design principles, and quality control
that is even stricter than Nikon’s long-inherited standards
are newly established. The title of the S-Line is reserved only
for lenses that have cleared these more rigorous standards
for evaluating various factors, including MTF performance.
While utilizing the advantage of outstanding flexibility in
lens design of the new Nikon Z mount, the S-Line lenses
achieve outstanding imaging performance by integrating
the tradition of Nikon’s optical design technologies with
the latest optical design technologies. The S-Line lenses
including f/1.8 prime lenses and a fixed f/4 zoom lens will
totally change the perception from that of the conventional
lenses associated with their specifications. Every S-Line
model features the refined, glistening silver-colored line
and the NIKKOR emblem with a decorative “S” on the
lens barrel. The “S” represents the first letter of various
words such as “Superior”, “Special” and “Sophisticated.” It
also stands for silver-colored line. All of the S-Line lenses
employ Nano Crystal Coat, and will also incorporate such
new technologies as ARNEO Coat and a multi-focusing
system. The elaborately crafted exterior design and optical
performance attained at an extremely high level make the
S-Line lenses as pleasurable to own as they are to use.
