Compact, Lightweight Superzoom lens,
with high zoom ratio 11:1
Sigma Corporation is pleased to announce the
launch of the new 18-200 F3.5-6.3
DC OS lens.
11.1 high zoom
ratio lens is designed exclusively for digital
SLR cameras and incorporates Sigma’s original OS
(Optical Stabilizer) technology.
This high ratio zoom lens incorporates
Sigma’s original OS (Optical Stabilizer)
function and exclusively designed for digital
SLR cameras. It is perfectly suitable for
low light conditions, indoors, at dusk and
telephoto range. SLD (Special Low
Dispersion) glass and aspherical glass provide
excellent correction for all types of
aberrations. This lens has a minimum
focusing distance of 45cm (17.7”) throughout the
entire zoom range and has a maximum
magnification of 1:3.9. The inner focusing
system is suitable for using a petal-type lens
hood supplied and also circular polarizing
filters.
Sigma’s own unique technology OS
(Optical Stabilizer) function
The
18-200mm f3.5-5.6 OS is equipped with Sigma’s
own unique OS (Optical Stabilizer)
technology. This system uses two sensors
inside the lens to detect vertical and
horizontal movement of the camera by moving an
optical image stabilizing lens group, to
effectively compensate for camera shake.
It also automatically detects
panning movement of the camera and
compensate for camera shake when shooting moving
subjects such as motor sports.
Excellent Optical
Performance
A Special Low
Dispersion (SLD) lens and three aspherical glass
elements provide excellent correction for all
types of aberrations and produce a high level of
optical performance throughout the entire zoom
range. The super multi-layer lens coating
reduces flare and ghosting while producing the
best color balance.
Enables close-up photography
This lens has a minimum focusing distance of
45cm through entire zoom range with a maximum
magnification of 1:3.9 making it very convenient
for taking close-up pictures.
Inner focusing
system
Because the front of the lens
does not rotate, circular polarizing filters and
a petal-type hood can easily be used.
Magnification scale
A
magnification scale is displayed on the lens
barrel, ensuring ease of use.
Zoom lock switch
mechanism
A zoom lock switch
mechanism is provided to prevent the lens from
creeping due to its own weight.
*Vignetting will occur if the lens is used on
digital cameras with image sensors larger than
APS-C size or with 35mm SLR cameras.
