Camera Lenses : Sigma Corp. of America Ships Upgraded 50-150mm f/2.8 APO EX DC OS HSM LensApril 20, 2012
The lens utilizes an inner focusing and inner zooming system for convenient handling and this, along with its OS feature, makes it favorable for handheld, close-up photography. Additionally, the Hyper Sonic Motor (HSM) helps ensures quiet and high-speed autofocusing, while allowing full-time manual focus capability.
“This lens is a great addition to our lineup of telephoto lenses, and will be a fantastic tool for portrait, landscape and nature photography,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “This is our tenth telephoto lens with Optical Stabilizer technology and provides another option for photographers looking to produce high-quality images.”
Six SLD glass elements provide correction for all types of aberrations, and it has a rounded, nine-blade diaphragm that creates an attractive blur to the out-of-focus areas of the image. Additionally, super multilayer coatings reduce flare and ghosting to aid in sharp, high-contrast images even at the maximum apertures.
The addition of Sigma’s 1.4x EX DG APO and 2x EX DG APO teleconverters produce a 70-210mm f/4 autofocus telephoto zoom lens and a 100-300mm f/5.6 autofocus telephoto lens, respectively.
The Sigma 50-150mm f/2.8 APO EX DC OS HSM is available in Canon, Nikon and Sigma mounts. $1,099. sigmaphoto.com
