Sigma 18-50mm OS

The Sigma 18-50mm f2.8-4.5 DC OS HSM - Sigma fit is a large aperture standard zoom lens designed exclusively for digital SLR cameras with the smaller APS-C sized sensor. It incorporates the Optical Stabilisation function as well as an Hyper Sonic Motor, and offers a large aperture of f2.8 at 18mm wide angle. This large aperture combined with the OS anti-shake function is ideal for indoor photography as well as low lighting conditions. Two SLD (Special Low Dispersion) glass elements and three aspherical lenses provide excellent correction for all types of aberrations. The Super Multi-Layer Coating reduces flare and ghosting.
