Sigma 120-400mm f4.5-5.6 DG OS HSM Sony Mount
| Telephoto zoom lens incorporates Sigma's original OS (Optical Stabilizer) function | |
| This telephoto zoom lens incorporates Sigma's original OS (Optical Stabilizer) function. It offers the use of shutter speeds approximately 4 stops slower. The minimum focusing distance of 150cm (59.1") throughout the entire zoom range and maximum magnification of 1:4.2 make it useful for close-up photography. Three SLD (Special Low Dispersion) glass elements provide excellent correction for chromatic aberration. This lens is equipped with a rear focus system that minimizes fluctuation of aberration caused by focusing. High image quality is assured throughout the entire zoom range. This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focusing capability. It is also possible to attach the optional APO Tele Converters. | |

| Sigma's own unique OS (Optical Stabilizer) technology | |
| The lens is equipped with Sigma's own unique OS (Optical Stabilizer) function. This function uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilizer lens group to effectively compensate for camera shake. It offers the use of shutter speeds approximately 4 stops slower. Mode 1 is ideal for general photography, and Mode 2 is effective on moving subjects such as motor sports etc. |
*For Pentax and Sony mounts, it is not possible to use the AF and the built-in OS function of this lens when attaching it to film SLR cameras as well as Pentax *ist series and K100D.
*When using the OS function of a lens with a camera which incorporates a stabilizer unit, please turn the camera?s stabilizer unit off.
*For Nikon and Canon mounts, Optical Stabilizer (OS) function will not work with film SLR cameras except Nikon F6 and Canon EOS-1V.
