The lens is the fourth generation model in a popular zoom lens category and features a new optical stabilization system along with a new hypersonic autofocus motor HSM, which offers 1.3 times the torque than the previous one.

The lens is designed as a workhouse, it has dust and splash proof resistant and a lens barrel, which contains a large amount of metal but with external moving parts made from thermally stable composite TSC that is resistant to thermal expansion and contraction.

In terms of specs, the lens contains 19 elements in 14 groups and has three types of low-dispersion glass that offers superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion).  The lens features a brand new OS and highly efficient and fast AF system. It embodies all the technical qualities and finesse that define the high performance Sigma Global Vision Art series. The Aspherical element of lens uses Sigma’s groundbreaking thicker center glass design and highly precise polishing process and delivers the stunning images and bokeh effect.
