Two new tele converters for Sony mount telephoto lenses that support HSM
Sigma announced two APO Tele Converters for the Sony Mount, the APO TELE CONVERTER 1.4x EX DG and the APO TELE CONVERTER 2x EX DG. These tele converters are capable of maintaining the HSM function of telephoto lenses such as Sigma’s APO 70-200mm F2.8 II EX DG MACRO HSM and APO 50-150mm F2.8 II EX DC HSM while increasing the focal length by a factor of 1.4x or 2x.
