The Sigma 18-125mm f/3.8-5.6 DC OS HSM Lens offers a high zoom ratio lens solution to digital SLR cameras, allowing you to zoom from wide-angle to long telephoto. It provides the equivalent focal range of approx. 30-212mm when used with a Sigma digital SLR camera. This lens has now been updated with the OS (Optical Stabilizer) system, which minimizes image blur caused by camera shake, and offers the equivalent of shooting at a shutter speed 3-4 stops faster. This allows handheld telephoto zoom shooting even in poorly lit conditions.

The 18-125mm's optical design incorporates aspherical lenses and SLD (Special Low Dispersion) glass, which provides the utmost correction for all types of aberrations. It also enables this high zoom ratio lens to be housed in a compact and lightweight construction.

DC lenses are exclusively designed for digital SLR cameras. The image circle (rear of lens) is sized 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 OS system uses two sensors inside the lens to detect vertical and horizontal movement of the camera. It works by moving an optical image stabilizing lens group, to effectively compensate for camera shake. It automatically detects movement of the camera and compensates for camera shake when shooting moving subject such as motor sports.
Special Low Dispersion (SLD) glass, a molded glass aspherical element and two hybrid aspherical elements provide excellent correction for all types of aberrations.
Super Multi Layer (SML) coating reduces ghost and flare.

      Comments about 18-125mm f/3.8-5.6 DC OS HSM Lens for Sigma Digital SLR Camera:

      A real great lens for almost anything. A faster (lower f-number) lens is needed for great portraits but this lens performs really well. It is sharp, fast focus.
