Sigma has just announced the pricing on the upgraded version of their 50-150mm tele-zoom lens for DSLR cameras with APS-C sensors, the APO 50-150mm F2.8 EX DC OS HSM. The lens now features Sigma’s proprietary Optical Stabilizer (OS) technology, which offers the use of shutter speeds approximately four stops slower than would otherwise be possible. The Canon mount version of the lens will be available from next week, while the Nikon and Sigma mount versions will be available by the end of April. The lens sells for a street price of US-$ 1,099 and is available for pre-order at B&H Photo.
