With the widespread popularity of the small sensor APS-c format cameras, the standard “kit” lens is often supplied at a very attractive price. Unfortunately, some of those kit lenses may be lacking in features and in image quality. In order to offer photographers an alternative to the camera manufacturers’ lenses, we have introduced our own “standard zoom” lens. Sigma’s 18-50mm F2.8-4.5 DC OS HSM with an almost 3 to 1 zoom range, this compact lens is great for vacations scenic, quick snap shots of the kids playing in the backyard, a day at the beach or even casual portraits. Three Aspherical glass elements offer correction for distortion, two SLD (Special Low Dispersion) glass elements provide optimum color correction and sharpness
And Super Multi-Layer lens coating reduces flare and ghosting and assures high image quality throughout the entire zoom range. It employs Sigma’s state of the art technology to assure top quality images at a value price.

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

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