Details of where you have found the cheaper item.
The prices shown are an estimate based on the purchase of a single item with nothing else in your basket. The prices and options do not include shipping regulations and duties which will be checked in the checkout process.
At CVP we always strive to get your order to you as quickly as possible, but in the interest of clarity please note that next day is defined as the next working day (ie: excluding weekends, UK bank holidays and public holidays).
Orders placed and security cleared before 14:00GMT where all items are in stock will normally be dispatched on the same business day for ultimate delivery according to the shipping method selected.
Where an item is not physically in stock, the actual delivery time will be extended by the lead time for the product in question. Shipping to the Channel Islands, Northern Ireland, Republic of Ireland and some remote UK postcodes are not next day but 2 working days.

This Sigma DC series wide angle and standard zoom lens is made exclusively for APS-C size sensors and has been designed to give optimum performance within that format, as found on most DSLR cameras. Its constant f/2.8 maximum aperture provides an equally bright image throughout the zoom range, making for easier handholding and more predictable exposures. It also has an optical image stabiliser (OS) that compensates for camera shake, giving you up to 4 more stops of slower shutter speeds in any given lighting situation.
The construction of this fine optic includes FLD glass which is equal in performance to fluorite glass. The result is a drastic reduction of both primary and secondary chromatic aberrations (false colour fringe effects). This lens also includes two glass mould and one hybrid aspherical lens to give excellent sharpness at all zoom settings.
The Sigma 17-50mm EX lens has Super Multi Layer Coating to reduce ghosting and flare and it benefits from superior peripheral brightness (very little vignetting).
|Lens Construction||17 Elements in 13 Groups|
|Angle of View (for SD1)||79.7 - 31.7 degrees|
|Number of Diaphragm Blades||7 Blades (Rounded diaphragm)|
|Minimum Focusing Distance||28cm / 11in.|
|Filter Size||Diameter 77mm|
|Dimensions||Diameter 83.5mm x Length 91.8mm / 3.3in. x 3.6in.|
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 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 mould 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.
FLD ("F" Low Dispersion) glass elements
Two FLD ("F" Low Dispersion) glass elements, which have the performance equal to fluorite glass, compensate for colour aberration. In addition, two glass mould 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.
Fast and quiet AF Hyper Sonic Motor
The lens incorporates HSM (Hyper Sonic motor), ensuring fast and quiet AF.
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.
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.
