Item:116114952613Sigma 18-200mm F3.5-6.3 II DC OS HSM Lens for Nikon SLR Camera (OLD MODEL). 18-200mm F3.5-6.3 II DC OS HSM lens is ideal for travel
photography with a compact construction and length of just 87.7mm. This lens
features FLD (F Low Dispersion) glass elements, which have the performance
equal to fluorite glass and SLD (Special Low Dispersion) glass elements
providing excellent correction of color aberration. From the Manufacturer
Compact High Zoom Ratio Lens with OS (Optical Stabilizer)This 11.1x high zoom
ratio lens incorporates Sigma's original OS function and offers a broad
shooting range from wide angle to telephoto. The latest optical technology
enables easy handheld photography with a compact construction and length of
just 3.5”, making it ideal for various scenes such as landscape, general
photography and sport. This compact construction guarantees excellent
mobility. FLD ("F" Low Dispersion) glass elements, which have performance
equal to fluorite, SLD (Special Low Dispersion) glass elements, and aspherical
lens elements provide high image quality throughout the entire zoom range. The
HSM (Hyper Sonic Motor) ensures fast and quiet auto-focusing.Sony and Pentax
mounts are not incorporated with OS function.For Pentax mount, if the camera
body does not support HSM, auto focus will not be available.Compact whilst
keeping high optical performanceThe SIGMA 18-200mm F3.5-6.3 II DC OS HSM is
the successor to the SIGMA 18-200mm F3.5-6.3 DC OS/ HSM which was launched in
June 2007. This lens features the latest optical technology including FLD
glass elements and aspherical lens elements, making it compact with a length
of just 3.5” whilst keeping high rendering performance. This compact
construction guarantees excellent mobility.Superior image qualityOne FLD ("F"
Low Dispersion) glass element, which has performance equal to fluorite, and
two SLD (Special Low Dispersion) glass elements provide excellent correction
for color aberrations. Two glass mold aspherical and a hybrid aspherical lens
element ensure excellent correction for all types of aberrations. Together
they provide a high level of optical performance throughout the entire zoom
range.FLD glass is the highest level low dispersion glass available with
extremely high light transmission. This optical glass has a performance equal
to fluorite glass which has a low refractive index and low dispersion compared
to current optical glass. It also benefits from high anomalous
dispersion.These characteristics give excellent correction for residual
chromatic aberration (secondary spectrum) which cannot be corrected by
ordinary optical glass and ensures high definition and high contrast images.
No Super Multi-Layer Coating (left). With Super Multi-Layer Coating (right).
Super Multi-Layer CoatingThe Super Multi-Layer Coating reduces flare and
ghosting as well as providing sharp and high contrast images throughout the
entire zoom range. All DG and DC lenses in the current Sigma range feature
this original technology. In digital cameras, flare and ghosting may also be
caused by reflections between the image sensor and lens surfaces. Here too,
Sigma's Super Multi-Layer Coating is highly effective, assuring images of
outstanding contrast. No Optical Stabilizer (top). With Optical Stabilizer
(bottom). Sigma's own unique OS technologyThe OS system offers effective
correction of approximately 4 stops, making it ideal for handheld photography
of various scenes such as travel, general, and sport.Sony and Pentax mounts
do not incorporate Optical Stabilization. Hyper Sonic Motor High speed and
quiet AFHSM indicates lenses equipped with a Hyper Sonic Motor, driven by
ultrasonic waves. The HSM (Hyper Sonic Motor) ensures fast and quiet auto-
focusing. For Pentax mount, if the camera body does not support HSM, auto
focus will not be available.Rounded diaphragmThe polygonal shape of a
conventional iris diaphragm causes outo-focus light points to appear
polygonal. A rounded diaphragm is designed to produce rounded outo-focus light
points when opened to near maximum aperture. This creates attractive bokeh
effects in many situations, such as when photographing a subject against an
out-of-focus surface of water from which light is being reflected.Lens
ConstructionIn a conventional lens, focusing requires an extension of the
entire lens or the front lens group. However, to better accommodate
autofocusing mechanisms and closeup photography, a need has arisen for lenses
that do not change their length during focusing or suffer from focus-dependent
variation in aberration. Therefore, Sigma has developed focusing systems that
only move elements within the lens barrel. These incorporate smaller and
lighter moving lens elements which help improve auto-focus speed. With their
unchanging barrel length and small variation in the center of gravity, these
lenses also enhance balance and stability for the photographer. Furthermore,
since the front of the lens does not rotate, polarizing filters can be used
with extra convenience.Specifications Lens Construction 18 Elements in 14

ChartView Larger ImageMTF (Modular Transfer Function) is one of the
measurements that evaluates a lens' performance, and it contrasts sensitivity
at different spacial frequencies. The horizontal axis is in millimeters and
shows the distance from the center of the image toward the edges, and contrast
value (highest value is 1) is shown in the vertical axis.The readings at 10
lines per millimeter measure the lens' contrast ability (red lines), repeating
fine parallel lines spaced at 30 lines per millimeter measure the lens'
sharpness ability (green lines), when the aperture is wide open. Fine
repeating line sets are created parallel to a diagonal line running from
corner to corner of the frame, are called Sagittal lines (S) and sets of
repeating lines vertical to these lines are drawn, called Meridional (M) line
sets.DistortionView Larger Imageeffective distortion: When you take a picture
of a lattice pattern, it will appear as the blue dotted line shows. the red
line illustrates how the lattice pattern will appear in the actual picture
when any lens distortion is taken into account.relative distortion: In this
chart, the horizontal axis shows the ideal image height (the distance from the
center to the edge of the image [mm]). The vertical axis shows the extent of
distortion. The extent of the distortion is represented by how much Y, which
is the actual image height, grows (or shrinks) against Y0 which is the ideal
image height.Extent of distortion: D[%]=(Y-Y0/Y0)x100When you take the picture
of a square object, if the distortion amount show a minus value, the image
will be seen as expanded (Barrel distortion). If the distortion amount is a
plus value, it will be seen as a recessed (pincushi on distortion). When the
distortion value is close to 0, the appearance of distortion is very
minimal.VignettingView Larger ImageThe horizontal axis shows the image height
(the distance from the center to the edge of the image [mm]). The vertical
axis shows the amount of light in the image (based on the amount of light in
the image center being 100%). If the peripheral amount of light is lower than
the center, the four corners of the image will be darker (vignetting).
