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).

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 superior Stabilization. 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.

*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.

Compact construction

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.

No 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.

Fast and quiet AF

Hyper Sonic Motor

Hyper Sonic Motor

The lens incorporates HSM (Hyper Sonic motor), ensuring fast and quiet AF.

*For Pentax mount, if the camera body does not support HSM, auto focus will not be available.

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.

Rounded diaphragm

Rounded diaphragm

This lens has rounded 7 blade diaphragm which creates an attractive bokeh to the out of focus area of the image.

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.
*Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras.

Corresponding Digital SLR Camera

DC lenses have an image circle that covers APS-C size image sensors. Not for use on digital cameras having image sensors larger than APS-C size or on 35mm or APS film cameras, as vignetting will occur. The angle of view varies depending on which camera the lens is mounted on. To find the 35mm camera-equivalent focal length, multiply the DC lens focal length by the crop factor (digital multiplier) of 1.5, 1.6, or 1.7, depending on the brand of DSLR camera on which the lens will be used. To find which DC lens is equivalent to a full-frame lens, divide the focal length of the full frame lens by the same crop factor.
Sony and Pentax mounts are not incorporated with OS function.
AF will not function with Pentax ist* series and K100D DSLR cameras that do not support HSM.
The appearance and specification are subject to change without notice.

The new DG UV filters benefit from a super multi-layer lens coating developed to counteract the highly reflective characteristics of digital image sensors reducing both flare and ghosting. Black rimmed glass eliminate unnecessary internal reflections. The Sigma EX DG range comprises UV filters, which not only reduce ultraviolet light but are ideal for protecting the lens during general photography.

SIGMA DG WIDE CIRCULAR PL 77mm

UPC Code : 00-85126-92386-0

The new Circular PL filters benefit from a super multi-layer lens coating developed to counteract the highly reflective characteristics of digital image sensors reducing both flare and ghosting. Black rimmed glass eliminate unnecessary internal reflections. Circular Polarizing (CP) filters which eliminate reflections from subject such as glass and water and deepen the intensity of blue skies. The range of CP filters, with the exception of 86mm, 95mm and 105mm, is encased within ultra-thin metal ring that does not cause vignetting with wide-angle lenses. Each of these Sigma EX DG filters is designed to accept the front cap of the lens.
