Sigma 18-50mm f/3.5-5.6 DC AF Wide Angle Zoom Lens for Canon EOS Digital Rebel XT, XTi, XS, XSi, T1i, 7D, 10D, 20D, 30D, 40D, & 50D Digital SLR Cameras
Product Description
The 18-50mm f/3.5-5.6 DC lens was exclusively designed to suit the characteristics of digital SLR cameras. Ideal as a standard starter zoom lens, this lens provides an equivalent range of approx. 28-80mm when used with a Canon digital SLR camera (*). The use of aspherical lenses provides correction for various aberrations throughout the entire zoom range and produce a high level of optical performance.
DC lenses are exclusively designed for digital SLR cameras. The image circle (rear of lens) is made to match the smaller dimensions used for the image sensor on digital cameras. As a result these lenses are also more compact and lightweight, and are better matched to digital SLR cameras.

The image quality of the pictures is average (tested with Canon D450), but the bad part was Autofocus performance. It failed 50% of the time and worked mostly on the pictures were objects were at the same distance from the camera. If not, the AF sets for the lower part of the image most of the time (tested for several days with the same effect in all image conditions).
