High ratio zoom lens housed in a compact construction and incorporating Sigma?s original OS (Optical Stabilizer) function.
The Sigma Corporation is pleased to announce the new 18-125mm
F3.8-5.6 DC OS HSM. This high ratio zoom lens is designed exclusively
for digital SLR cameras and will be showcased at PMA, which starts on
January 31st, 2008 in Las Vegas, U.S.A.
This compact high zoom ratio lens is designed exclusively for
digital SLR cameras and incorporates Sigma?s original OS (Optical
Stabilizer) function. This system 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 offers the use of shutter speeds
approximately 4 stops slower. It is the ideal lens for several type of
photography such as wide-angle, telephoto and close-up. SLD (Special
Low Dispersion) glass, a molded glass aspherical lens and two
hybrid aspherical lenses provide excellent correction for all types of
aberrations. The super multi-layer coating reduces flare and ghosting.
High image quality is assured throughout the entire
zoom range. This lens has a minimum focusing distance of 35cm (13.8")
at all focal lengths, and has maximum magnification of 1:3.8, making it
ideal for close-up photography. This lens incorporates
HSM (Hyper Sonic Motor), which ensures a quiet and high-speed autofocus.
