Sigma 105mm F2.8 EX DG OS HSM Macro announced

Sigma just announced their latest macro lens : the Sigma 105mm f2.8 EX DG OS HSM. The lens update previous version by adding Optical Stabilizer technology

  • true 1:1 macro reproduction
  • OIS ( image stabilization )
  • suggested price : $1400 , but usually is going to be less than that.
  • a floating focusing system
  • support for Sigma’s APO teleconverter

I guess the suggested price is a bit expensive for a macro lens , especially when Nikon/Canon have it cheaper ( Nikon 105mm VR for $950 ). But if the quality is so much better then , why not? Can’t wait to see the reviews

Press Release:

Ronkonkoma, NY, June 28, 2011 – Sigma Corporation of America, a leading researcher, developer, manufacturer and service provider of some of the world’s most impressive lines oflensescameras and flashes, is pleased to announce that its newly upgraded 105mm F2.8 EX DG OS HSM Macro lens is now available for the MSRP of $1,400.

The updated 105mm F2.8 EX DG OS HSM Macro lens now features Sigma’s own proprietary Optical Stabilizer (OS) technology, which allows for high-performance, handheld, close-up photography. The telephoto reach makes it a perfect lens for capturing images of insects and small creatures. Additionally, the wide maximum aperture combined with a short telephoto focal length make it very favorable for facial portraiture at lower magnification. A Special Low Dispersion (SLD) lens and one high refractive index SLD lens provide excellent corrections for all types of aberration and distortion.

“This lens is a fantastic addition to our extensive lineup of macro lenses,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “This is our fourth prime macro lens and the second of which that now includes our Optical Stabilization technology, which steadies the image for handheld use. This is yet another example of Sigma’s dedication to providing an array of unique lens that capture incredible imagery.”

Sigma’s Hyper Sonic Motor (HSM) feature ensures quiet and high-speed autofocus as well as full-time manual focus capability. This lens also has a rounded nine-blade diaphragm that creates an attractive blur to the out-of-focus areas of the image.

The 105mm F2.8 EX DG OS HSM Macro features a floating focusing system that moves two different lens groups in the optical path to different positions. This system compensates for astigmatic aberration and spherical aberration, and provides extremely high optical performance from infinity to 1:1 macro. The super multi-layer coating reduces flare and ghosting, providing high contrast images. It is also possible to use this lens with Sigma’s APO teleconverters.

This announcement comes as part of an ongoing celebration of the company’s 50th anniversary. Find out about special anniversary activities and features, including product videos, photo sharing, photography tips and monthly chances to win Sigma products by visiting the anniversary web page.
