This compact high zoom ratio lens is designed exclusively for digital SLR cameras and incorporates Sigma?s original OS (Optical Stabilizer) function. This system uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilizing lens group to effectively compensate for camera shake. It offers the use of shutter speeds approximately 4 stops slower. It is the ideal lens for several type of photography such as wide-angle, telephoto and close-up. SLD (Special Low Dispersion) glass, a molded glass aspherical lens and two hybrid aspherical lenses provide excellent correction for all types of aberrations. The super multi-layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. This lens has a minimum focusing distance of 35cm (13.8") at all focal lengths, and has maximum magnification of 1:3.8, making it ideal for close-up photography. This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed autofocus.

Comments about Sigma Sigma 18-125mm F/3.8-5.6 OS HSM Lens f/ Nikon:
I purchased this lens based on my experiance with the 105mm SIGMA macro lens I own. Like the 105mm the construction of the lens is solid. Unlike the 105mm the sharpness is lacking. After taking about 100 shots with this lens I've yet to find its sweetspot in the aperture range. The focus motor is fast and fairly silent however this is a slow lens. Even on a clear sunny day with a polarizing filter attached I found it difficult to get a shot at f16 and iso 200 somewhere between 18 and 24mm without having to use a tripod. Also the OS needs to be turned OFF when removing and attaching the lens to the camera body, keep this in mind if you change lens often.
Over all this is a decent lens but the detail just is not there.
