Large aperture standard zoom lens with a minimum focal length of 17mm, designed exclusively for digital SLR cameras and incorporating Sigma's original OS (Optical Stabilizer). The OS function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. The lens has a compact construction with an overall length of 91.8mm. This compact and lightweight construction makes the lens ideal for travel photography. Two FLD ("F" Low Dispersion) glass elements, two glass mold and one hybrid aspherical lens provide excellent correction for all types of aberrations. This lens has superior peripheral brightness and provides sharp and high contrast images even at the maximum apertures. The incorporation of HSM (Hyper Sonic Motor) provides fast and quiet AF. *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.
FLD (“F” Low Dispersion) glass elements
Two FLD (“F” Low Dispersion) glass elements, which have the performance equal to fluorite glass, compensate for color aberration. In addition, two glass mold elements and one hybrid aspherical lens give excellent correction for field curvature and astigmatism. High definition images are ensured 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.
Sigma’s own unique OS (Optical Stabilizer) technology
The 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.
*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.
F2.8 Large aperture throughout the entire zoom range
The large aperture provides a bright viewfinder image, helping the photographer confirm accurate focusing. It is also ideal for emphasizing the subject by creating a natural, blurred background and allowing the use of fast shutter speeds.
Covering a wide range of focal lengths from 17mm
This lens covers a wide range of focal lengths from 17mm and has an equivalent angle of view of a 25.5-75mm with a 35mm SLR camera. It is ideal for portraits, landscapes and general photography.
*The angle of view varies depending on which camera the lens is mounted on.
The lens has a compact construction with a diameter of 83.5mm, overall length of 91.8mm and weight of 565g. This compact and lightweight construction makes it ideal for travel photography.
Super Multi-Layer Coating
The Super Multi-Layer Coating reduces flare and ghosting as well as providing sharp and high contrast images throughout the entire zoom range.
Superior peripheral brightness
This lens has superior peripheral brightness and provides sharp and high contrast images even at the maximum apertures.
Close focusing capability
This lens has a minimum focusing distance of 28cm throughout the entire zoom range and a maximum magnification ratio of 1:5.
Inner focusing system
The inner focusing system eliminates front lens ration, making the lens particularly suitable for using the supplied petal-type hood and circular polarizing filters.
