Overview

Description by Sigma:

  • For use with smaller chip APS-c cameras only
  • Offers Sigma’s OS System (Optical Stabilization) allowing handheld photography even in low-light situations
  • HSM (Hyper-Sonic Motor) ensures a quiet and high-speed auto focus
  • Internal focus & zooming systems
  • Compact and lightweight at only 14 ounces
  • A lens hood and front & rear lens caps are included with the lens.

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.

*3 Nikon Mount in motor lens: compatible with D40, D40x, D60, D3000, D5000

Reviews

"This lens is largely constructed from plastic with a brass lens mount. The exterior has a powder coated finish typical of Sigma lenses. This finish adds a quality feel to the lens when new, but in my experience it soon marks with normal use. Much of the lens barrel is taken up by the zoom and focus rings, which have nice wide rubber grips on them. The focus ring rotates during autofocus and can sometimes catch fingers
