It replaces the 180mm f\/3.5 EX DG macro in the lineup. Improvements (in addition to 1:1 magnification) include an Optical Stabilizer that Sigma says will allow users to shoot at up to four stops slower; three FLD glass elements which are said to correct for color aberrations, and internal focusing. A Hyper Sonic Motor is claimed to be quick and quiet, and the lens&#8217;s nine-blade diaphragm blades are rounded for attractive blur.<\/p>\n<p><img decoding=\"async\" alt=\"\" src=\"\/alc\/wp-content\/uploads\/alc_images\/article13495_1.jpg\" \/><\/p>\n<p>Introducing the Digital Neo (DN) Line<br \/>\nSigma also announced a new line of lenses for Mirrorless Interchangeable Lens Compacts (MILC) in Micro Four Thirds mounts and E-Mounts. The first two lenses are the 30mm f\/2 EX DN and the 19mm f\/2 EX DN lenses. As a Micro Four Thirds lens, the 30mm provides the coverage of a 60mm lens on a 35mm sensor camera. On a Sony NEX, it covers the equivalent of a 45mm lens. The 19mm offers 38mm and 28.5mm (35mm equivalent) coverage on Micro Four Thirds and Sony NEX, respectivelay. Both lenses have rounded seven-blade diaphragms for smooth bokeh.<\/p>\n<p><img decoding=\"async\" alt=\"\" src=\"\/alc\/wp-content\/uploads\/alc_images\/article13495_2.jpg\" \/><\/p>\n<hr \/>\n<p>For details, read both Sigma press releases:<\/p>\n<p>Sigma Corporation of America announces world\u2019s first 1:1 180mm F2.8 macro lens<br \/>\nNew fast and stabilized lens announced at Consumer Electronics Show 2012<\/p>\n<p>RONKONKOMA, NY and LAS VEGAS, NV Jan. 9, 2012 \u2013 Sigma Corporation, a leading researcher, developer, manufacturer and service provider of some of the world&#8217;s most impressive lines of lenses, cameras and flashes, is pleased to announce the Sigma APO Macro 180mm F2.8 EX DG OS HSM, the world\u2019s first 180mm macro lens that offers a magnification ratio of 1:1 and a large maximum aperture of F2.8.<\/p>\n<p>As the successor to Sigma\u2019s earlier 180mm F3.5 EX DG macro lens, the new APO Macro 180mm F2.8 EX DG OS HSM lens now boasts the company\u2019s 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, this lens offers the use of shutter speeds approximately four stops slower than would otherwise be possible, enabling handheld close-up photography. Three \u201cF\u201d 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.<\/p>\n<p>\u201cOur first 180mm macro was very popular with macro photographers and we\u2019re 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,\u201d said Mark Amir-Hamzeh, president of Sigma Corporation of America. \u201cWe\u2019ve released some really incredible products in the past year \u2013 there\u2019s truly something in our lineup for every type and level of photographer.\u201d<\/p>\n<p>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 at the maximum aperture. The incorporation of Sigma\u2019s Hyper Sonic Motor (HSM) ensures quiet and high-speed autofocus, as well as full-time manual focus capability. The macro lens has a rounded nine-blade diaphragm to create an attractive blur to the image\u2019s 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 like butterflies.<\/p>\n<p>Sigma Corporation of America announces prime lenses for mirrorless interchangeable lens cameras at CES 2012<br \/>\nNew lenses and product line designed for Micro Four Thirds, E-mount systems<\/p>\n<p>RONKONKOMA, NY and LAS VEGAS, NV, Jan. 9, 2012 \u2013 Sigma Corporation of America today announced the launch of its new line of Micro Four Thirds system and E-mount lenses for mirrorless interchangeable lens cameras from the Consumer Electronics Show (CES) 2012 in Las Vegas, NV.<\/p>\n<p>The leading researcher, developer, manufacturer and service provider of some of the world\u2019s most impressive lines of lenses, cameras and flashes, has made its entr\u00e9e into the mirrorless interchangeable lens category with the introduction of its Digital Neo (DN) line, which will first include the 30mm F2.8 EX DN and the 19mm F2.8 EX DN lenses in Micro Four Thirds mounts for Olympus and Panasonic, and E-mount for Sony NEX-series cameras. Pricing and availability are pending.<\/p>\n<p>\u201cThe launch of our DN series with two fast prime lenses demonstrates our commitment to being a leader in innovation and quality, and providing photographers with excellent choices for lenses in this exciting new camera category,&#8221; said Mark Amir-Hamzeh, president of Sigma Corporation of America. \u201cSigma lenses empower photographers to be more creative with their photography, and we\u2019re absolutely thrilled to be embarking on this new journey with products for mirrorless interchangeable lens cameras for Micro Four Thirds and NEX mount systems.&#8221;<\/p>\n<p>The Sigma DN line of high-performance lenses is designed exclusively for mirrorless interchangeable lens cameras. This lens design and technology ensures high optical performance and compact, lightweight construction. The DN lenses\u2019 superior telecentric optical design also assures sharp- and high-resolution image quality across the entire image plane.<\/p>\n<p>The 30mm F2.8 EX DN and the 19mm F2.8 EX DN lenses are both equipped with Sigma\u2019s Super Multi-Layer Coating to reduce flare and ghosting, while providing sharp and high-contrast images, even at the maximum aperture. The lenses also benefit from a newly developed linear autofocus (AF) motor, which moves the lens unit directly without the need for gears or the drive of other mechanical parts. This system ensures accurate and quiet autofocusing, making both the 30mm F2.8 EX DN and the 19mm F2.8 EX DN suitable for video recording as well as still photos.<\/p>\n<p>The Sigma 30mm F2.8 EX DN has the equivalent angle of view of a 60mm lens (35mm equivalent focal length) on the Micro Four Thirds system and 45mm (35mm equivalent focal length) on the E-mount system. It has a minimum focusing distance of 11.8 inches and a maximum magnification ratio of 1:8.1. The 30mm F2.8 EX DN has two glass mold aspherical lenses, including a double-sided aspherical lens, to provide excellent correction for all types of aberration, as well as an inner focusing system that corrects the fluctuation of aberration to maintain image quality regardless of the focal distance. It also features a rounded, seven-blade diaphragm to deliver a smooth rendering of the out-of-focus areas of the image.<br \/>\nThe Sigma 19mm F2.8 EX DN is a wide angle lens with the equivalent angle of view of a 38mm (35mm equivalent focal length) on the Micro Four Thirds system and 28.5mm (35mm equivalent focal length) on the E-mount system. It has a minimum focusing distance of 7.9 inches and a maximum magnification ratio of 1:7.4. Three glass mold aspherical lenses provide excellent correction for distortion, color aberration and field curvature, and an inner focusing system corrects the fluctuation of aberration to maintain image quality regardless of the focal length. The 19mm F2.8 EX DN lens features a rounded, seven-blade diaphragm, which ensures smooth rendering of the out-of-focus areas of the image.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><span style=\"color: rgb(51, 51, 51);
