The Sigma 50-150mm F2.8 EX DC APO HSM II is a compact fast telephoto 3x zoom lens with an HSM autofocus drive and constant aperture throughout the entire range of focal lengths.
The Sigma 50-150 mm f/ 2.8 EX DC APO HSM II is dedicated for small-format DSRL cameras and cannot be used on full-format and film cameras.
Its optical scheme has four SLD elements to effectively resist all types of chromatic aberrations. The super multi-coating reduces flare and halation, and corrects color rendering.
The HSM autofocus drive provides noiseless and high-speed autofocusing with the possibility of a full-time manual focusing without switching to the manual mode. The system of internal focusing and zooming does not change the size of the Sigma 50-150 mm f/ 2.8 EX DC APO HSM II. Besides, the front element does not rotate, which makes it possible to use a petal hood and a polarizer.
The Sigma 50-150 mm f/ 2.8 EX DC APO HSM II is compatible with the Sigma 1.4x EX DG APO or 2x EX DG APO teleconverters. When coupled with the teleconverters, a range of focal lengths of 70-210/4.0 or 100-300/5.6 respectively can be achieved.
In 2012 a new version of the lens equipped with a stabilizer and a different optical scheme was released.
