CES/PMA 2012: Sigma Debuts 180mm F/2.8 Macro Lens and Compact System Camera Lenses

January 10, 2012

Sigma debuted a new 180mm f/2.8 macro lens for digital SLRs and a new line of Micro Four Thirds and E-mount lenses for mirrorless interchangeable lens compact system cameras at the CES show in Las Vegas this week .

The 180mm f/2.8 lens is a successor to the older 180mm F3.5 EX DG macro and adds Sigma’s proprietary Optical Stabilizer (OS) technology and a wide f/2.8 aperture to allow for faster shutter speeds in low light and a narrow depth of field.

Sigma also took the wraps off a 30mm f/2.8 EX DN and 19mm f/2.8 EX DN lenses in the Micro Four Thirds mounts for Olympus and Panasonic, and E-mount for Sony NEX-series cameras. Pricing and availability of these lenses has not been announced yet.

More details in the two press releases below.


PRESS RELEASE

Sigma Corporation of America announces world’s first 1:1 180mm F2.8 macro lens
New fast and stabilized lens announced at Consumer Electronics Show 2012

RONKONKOMA, NY and LAS VEGAS, NV Jan. 9, 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, is pleased to announce the Sigma APO Macro 180mm F2.8 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 F2.8.

As the successor to Sigma’s earlier 180mm F3.5 EX DG macro lens, the new APO Macro 180mm F2.8 EX DG OS HSM lens now boasts the company’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, this 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 correction for color aberrations, and an inner focusing system minimizes aberrations that occur as shooting distances change.

“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.”

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’s 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’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 like butterflies.

The announcement was made at the Consumer Electronics Show (CES) 2012 in Las Vegas, NV, where Sigma Corporation is exhibiting this week in the Las Vegas Convention Center’s Central Hall at booth 8960. The company also announced the launch of a new product line and two new lenses that are specifically designed for use with Micro Four Thirds and E-mount mirrorless interchangeable lens camera systems. The pricing and availability of all of these new lenses are pending.

PRESS RELEASE

Sigma Corporation of America announces prime lenses for mirrorless interchangeable lens cameras at CES 2012

New lenses and product line designed for Micro Four Thirds, E-mount systems

RONKONKOMA, NY and LAS VEGAS, NV, Jan. 9, 2012 – 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.

The leading researcher, developer, manufacturer and service provider of some of the world’s most impressive lines of lenses, cameras and flashes, has made its entrée 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.

“The 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,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “Sigma lenses empower photographers to be more creative with their photography, and we’re absolutely thrilled to be embarking on this new journey with products for mirrorless interchangeable lens cameras for Micro Four Thirds and NEX mount systems.”

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’ superior telecentric optical design also assures sharp- and high-resolution image quality across the entire image plane.

The 30mm F2.8 EX DN and the 19mm F2.8 EX DN lenses are both equipped with Sigma’s 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.

•    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.
•    The 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.
