Sigma calls its new APO Macro 180mm f/2.8 EX DG OS HSM “the world’s first 180mm macro lens that offers a magnification ratio of 1:1 and a large maximum aperture of f/2.8.”
As the successor to its 180mm f/3.5 EX DG macro lens, the new Sigma APO 180mm f/2.8 Macro lens now boasts the company’s Optical Stabilizer (OS) technology and a wide f/2.8 aperture to allow faster shutter speeds for narrow depth of field. With the OS feature, this lens offers the use of shutter speeds approximately four stops slower than would otherwise be possible, enabling handheld close-up photography.
“Our first 180mm macro was very popular with macro photographers and we’re certain that discerning photographers will be very impressed with its new technical and performance upgrades. The Optical Stabilizer technology and faster maximum aperture will make it even easier for users to capture the close-up, intricate details in the tiny world around them,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “We’ve released some really incredible products in the past year—there’s truly something in our lineup for every type and level of photographer.”
Three “F” Low Dispersion (FLD) glass elements, which have a performance equal to fluorite glass, are included to provide correction for color aberrations, and an inner focusing system minimizes aberrations that occur as shooting distances change. The lens also features super multi-layer coating; Sigma’s hypersonic motor (HSM) to ensure quiet, high-speed autofocus, as well as full-time manual focus capability; and a focusing distance of 18.5 inches, which is a greater working distance than shorter focal length macro lenses.
Sigma’s 1:1 180mm f/2.8 macro lens will come in mounts for Nikon, Canon, Pentax, Sigma, and Sony cameras. Pricing is not yet available. sigmaphoto.com
