Two New Lenses From Sigma

The APO 50-150mm F2.8 II EX DC HSM is a large aperture (F2.8), lightweight and compact telephoto zoom lens that was designed specifically for use with dSLRs that feature an APS-C size image sensor. Other features include Sigma's HSM (Hyper Sonic Motor) focusing system and four SLD elements to help reduce chromatic aberrations. Sigma also introduced the APO 70-200mm F2.8 II EX DG MACRO HSM. This is yet another large aperture zoom lens (F2.8) that includes two SLD (Special Low Dispersion) and three ELD (Extraordinary Low Dispersion) elements that help minimize all types of aberrations. Both models feature Tele Converters to further extend their zooming capabilities.
