AF NIKKOR LENSES
PHOTO - VIDEO - PRO AUDIO
When it comes to choosing photographic equipment, perhaps the
most important decision a photographer faces is which lens system
to use. For the majority of professional photographers, that choice
is simple: Nikkor. The reasons for this are many, not the least of
which is Nikon’s total commitment to controlling every aspect
of lens manufacturing. This no-compromise attitude toward
manufacturing extends performance. For each Nikkor lens is
designed to function seamlessly with Nikon SLRs. This is exemplified most clearly in the legendary Nikon F mount. Even the
most advanced Nikkor lenses incorporate this standard for its consistency and reliability. This design also ensures that when
Nikon introduces new cameras with revolutionary features such as 3D Color Matrix Metering and Multi-Sensor Balanced
Fill-Flash, you’ll always have an array of lenses available to handle these advances.
AF D-type Nikkor Lenses
AF Nikkor D-type lenses are special because they relay subject-to-
camera distance information to AF Nikon camera bodies that use the
information. This makes possible new technologies like Nikon’s 3D
Color Matrix Metering and 3D Multi-Sensor Balanced Fill-Flash.
Aspherical Lens Elements
Nikon introduced the first photographic lens with aspherical lens
elements in 1968. Aspherical lenses minimize the problem of coma and
other types of lens distortion—even when used at the widest aperture.
They are particularly useful in correcting the distortion in wide-angle
lenses. In addition, use of aspherical lenses contributes to a lighter and
smaller and lens design.
ED Glass
Nikon developed ED (Extra-low Dispersion) glass to make telephoto
lenses that offer superior sharpness and color correction by minimizing
chromatic aberration. (Chromatic aberration is a type of image and
color distortion that occurs when light rays of varying wavelengths
pass through optical glass). ED lenses deliver stunning sharpness and
contrast even at their largest maximum apertures.
Nikon Integrated Coating (NIC)
To enhance the performance of lens elements, Nikon employs
sophisticated multi-layer coating to help reduce ghost and flare to
negligible levels. Nikon Integrated Coating (NIC) minimizes reflections
over a wide wavelength range, and enhances color balancing. It is
carefully integrated into the design of each Nikkor lens type, with the
coatings calculated to match the lens type and glass.
Close-Range Correction System
Providing superior picture quality at close focusing distances and
increasing the close focus range, the Close-Range Correction (CRC)
system is one of Nikon’s most important focusing innovations. With
CRC, the lens elements are configured in “floating element” design
wherein each lens group moves independently to achieve focusing.
This ensures superior lens performance even when shooting very close.
Internal Focusing
Imagine being able to focus a lens without it changing in size. Nikon’s IF
technology enables just that. All internal optical movement is limited to
the interior of the non-extending lens barrel. This allows for a more
compact, lightweight construction as well a closer focusing distance.
Nano-Crystal Coat
Nano-Crystal Coat (NCC) is derived from Nikon’s exclusive nano-tech-
nology. Using microscopic crystal particles, NCC endows a lens with a
super-low refractive index, providing superior anti-reflective properties
that virtually eliminate ghosting and flare and provide clear and vivid
images when shooting under strong sunlight or inside under spotlights.
AF-S Technology
AF-S lenses feature Nikon’s Silent Wave Motor (SWM) which converts
“traveling waves” into rotational energy to focus the optics. This enables
high-speed autofocusing that’s extremely accurate and quiet.
M/A Mode
AF-S lenses also feature Nikon’s exclusive M/A mode, that allows
switching from autofocus to manual operation with virtually no time
lag – even during AF servo operation.
Vibration Reduction System
Stability is critical for telephoto and close-up photography. Nikon
Vibration Reduction (VR) technology automatically compensates for
camera shake to ensure sharp pictures at slower shutter speeds. If you
can steadily hand-hold at 1/125 second, VR will enable you to shoot at
about 1/15 second. The system even automatically detects and compen-
sates for panning when the camera is following a moving subject.
Defocus Image Control
A set of unique lenses for unique portraits, Defocus-Image Control
allows photographers to control the degree of spherical aberration in
the foreground or background by rotating the lens’ DC ring. This will
create a rounded out-of-focus blur that is ideal for portrait photography.
