13.8x high zoom ratio lens designed exclusively for digital SLR cameras and incorporating Sigma's original Optical Stabiliser function.
This high zoom ratio lens is designed exclusively for digital SLR cameras and incorporates Sigma's original OS (Optical Stabiliser) technology. This system offers the use of shutter speeds approximately 4 stops slower. Pentax and Sony mount lenses are also equipped with the OS function as it is possible to use this with camera bodies which already incorporate a built-in anti-shake system. Four SLD (Special Low Dispersion) glass elements and three aspherical lenses provide excellent correction for all types of aberrations. High image quality is assured throughout the entire zoom range. The HSM (Hyper Sonic Motor) ensures fast and quiet auto-focusing. This lens has a minimum focusing distance of 45cm (17.7in) and a maximum magnification ratio of 1:3.4, making it convenient for close-up photography.
