From Sigma Corporation of America: Sigma Corporation of America announces pricing and availability for 180mm F2.8 macro lens World’s first 1:1 180mm F2.8 macro lens arrives in the US in July for street price of $1,699
RONKONKOMA, NY July 13, 2012 – Sigma Corporation, a leading researcher, developer, manufacturer and service provider of some of the world's most impressive lines of lenses, cameras and flashes, has announced that the Sigma APO Macro 180mm F2.8 EX DG OS HSMwill be available in the United States on July 27 for the street price of $1,699.
The new APO Macro 180mm F2.8 EX DG OS HSM lens
boasts Sigma’s proprietary Optical Stabilizer (OS) technology and a wide F2.8 aperture to allow faster shutter speeds for narrow depth of field. With the OS feature, the lens offers the use of shutter speeds approximately four stops slower than would otherwise be possible, enabling handheld, close-up photography. Three “F” Low Dispersion (FLD) glass elements, which have a performance equal to fluorite glass, are included to provide excellent correction for color aberrations, and an inner focusing system enables this lens to photograph objects precisely throughout the entire focusing range. Overall length does not change during focusing.
“Macro photography is becoming quite popular and we’ve been growing our lineup of macro lenses as a result,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “We’re filling a gap in the industry by introducing the world’s first 1:1 180mm F2.8 lens to the market. The Optical Stabilizer technology and the larger focusing distance also provide photographers with more control for highly sensitive subjects that are on the move, like butterflies and insects.”
Equipped with the Super Multi-Layer Coating feature, the APO Macro 180mm F2.8 EX DG OS HSM lens reduces flare and ghosting, and delivers sharp and high contrast images, even in backlit conditions. The incorporation of Sigma’s Hyper Sonic Motor (HSM) ensures quiet and high-speed autofocus, as well as full-time manual focus override capability. The macro lens has a rounded nine-blade diaphragm to create an attractive blur to the image’s out-of-focus areas. At 1:1 magnification, this lens has a focusing distance of 18.5 inches, which is a greater working distance than shorter focal length macro lenses, making it advantageous when taking pictures of highly sensitive subjects. It is also compatible with Sigma’s 1.4x EX DG APO and 2x EX DG APO Tele Converters.
