Product Description

Large aperture telephoto zoom lens, designed exclusively for digital SLR
cameras and incorporating Sigma's original Optical Stabilizer function.
This large aperture telephoto zoom lens incorporates Sigma's original OS
(Optical Stabilizer) function which offers the use of shutter speeds
approximately 4 stops slower than would otherwise be possible. This enables hand
held tele-photography easily. Six SLD glass elements provide excellent
correction for color aberration. The Super Multi-Layer Coating reduces flare and
ghosting and provides high image quality throughout the entire zoom range. HSM
ensures fast and quiet auto-focusing as well as full-time manual focusing
capability. This lens incorporates an inner focusing and inner zooming system.
The overall length of the lens does not change during focusing and zooming,
ensuring convenient handling. This lens has a minimum focusing distance of 80cm
and maximum magnification of 1:6.3. The rounded 9 blade diaphragm creates an
attractive blur to the out of focus areas of the image. Sigma's APO TELE
CONVERTER can also be used with this lens if a longer focal length is required
Sigma's own unique OS technology
This lens is equipped with Sigma's own unique OS (Optical Stabilizer) function.
This system allows the photographer to use shutter speeds approximately 4 stops
slower than would otherwise be possible. As compensation for camera shake is
visible in the view finder, the photographer can easily check for accurate focus
and ensure there is no subject movement. The Optical Stabilizer unit has two
modes, Mode 1 is ideal for general photography and Mode 2 is designed for
panning subjects such as racing cars.
Superior image quality
Six SLD (Special Low Dispersion) glass elements provide excellent correction for
color aberration. The lens design provides correction for spherical aberration,
ensuring high images quality throughout the entire zoom range.
F2.8 Large aperture throughout the entire zoom range
The narrow depth of field enables photographers to emphasize the subject and the
large aperture provides a bright viewfinder image. Together with the OS
function, they help the photographer confirm accurate focusing.
No Super Multi-Layer Coating
The Super Multi-Layer Coating reduces flare and ghosting and provides high image
quality even in backlight conditions.
HSM (Hyper Sonic Motor)
Hyper Sonic Motor
The Hyper Sonic Motor (HSM) ensures a silent, high-speed AF function as well as
full-time manual focusing capability.
Close focusing capability
This lens has a minimum focusing distance of 80cm and maximum magnification of
1:6.3, making it ideal for close-up photography.
Convenient handling
This lens incorporates an inner focusing and inner zooming system. The
overall length of the lens does not change during focusing and zooming, ensuring
convenient handling. The inner focusing system also eliminates front lens
rotation, making the lens particularly suitable for using circular polarizing
filters. A removable tripod collar (TS-21) is included as a standard component.
Rounded diaphragm
This lens has a rounded 9 blade diaphragm which creates an attractive blur
to the out of focus areas of the image.
APO Tele-Converter (Optional)
The addition of Sigma's 1.4x EX DG APO or 2x EX DG APO TELE CONVERTER
produces a 70-210mm F4 AF telephoto zoom lens or a 100-300mm F5.6 AF telephoto
zoom lens respectively.
