AF LENSES for Canon, Nikon, Sony/Minolta, Pentax & Sigma
WIDE ANGLE & STANDARD ZOOM LENSES
18-200mm F3.5-6.3 DC
An extended range super zoom lens designed exclusively for digital SLR cameras, it covers a wide range
of focal lengths from wide-angle to telephoto. Two Special Low Dispersion (SLD) glass elements and
two hybrid aspherical lenses offer the utmost correction for all types of aberrations, and enables a
compact and lightweight design. Only 3.1˝ long and weighs just 14.3oz. Lens coating reduces flare
and ghost, which is a common problem of digital cameras and also creates an optimum color balance.
Minimum focusing distance of 17.7˝ at all focal lengths and has maximum magnification of 1:4.4.
Inner focusing system prevents the front of the lens from rotating, making it suitable for using circular
polarizing filters and petal shaped lens hoods. A zoom lock switch eliminates ‘zoom creep’ during
transportation. Filter size is 62mm.
20-40mm f2.8 EX DG Aspherical
The 20-40mm lens with f2.8 throughout its zoom range, offers an ultra-wide 94.5° to near-standard
56.8° angle of view, for photographers to shoot more creatively from various angles and zoom
perspectives. With a fast f2.8 maximum aperture superior peripheral brightness is ensured. This lens
is perfectly suited for indoor shootings even in dim light without worrying about blurring in photos.
Minimum focusing distance is 11.8˝ useful for closeups, giving photographers plenty of capability to
use the zoom to adjust composition and concentrate on detail, as desired. Maximum magnification
is 1:4.6. Aspherical lens elements in front and rear lens groups compensate for astigmatic and
spherical aberration, respectively. Among the practical high-performance features of the lens are
DF (Dual Focus) mechanism for optimal handling stability during autofocus operation; a wider-than-
conventional focal ring for superior manual focusing operation; and an inner focusing system that
eliminates front lens rotation during focusing, and allows use of the standard petal-type hood
accessory, which is excellent at blocking out extraneous light. Filter size is 82mm.
18-200mm F3.5-6.3 DC OS
Identical to the 18-200mm f/3.5-63 DC (above), except this lens is also equipped with Sigma’s own
unique OS (Optical Stabilizer) function. It uses two sensors inside the lens to detect vertical and
horizontal movement of the camera and works by moving an optical image stabilizing lens group, to
effectively compensate for camera shake. It automatically detects movement of the camera and
compensates for camera shake when shooting moving subject such as motor sports. Like the 18-200mm
f/3.5-63 DC (above) it has two SLD(Special Low Dispersion) glass elements and two aspherical lenses to
provide excellent correction for all types of aberrations. The super multi-layer lens coating reduces flare
and ghosting. This lens provides superior image quality throughout the entire zoom range. An inner
focusing system eliminates front lens rotation, making the lens particularly suitable for using circular
polarizing filters and the petal-type lens hood supplied.
