Ronkonkoma, N.Y. -
introduced Tuesday a newly upgraded version of its 105mm F2.8 EX DG OS HSM macro lens.
The 105mm F2.8 EX DG OS HSM macro lens carries a $1,400 suggested retail and now features Sigma's proprietary Optical Stabilizer (OS) technology.
Sigma said the telephoto reach and macro focusing make the lens perfect for capturing images of insects and small creatures.
When used with a wide maximum aperture and short telephoto focal length, the lens is also well suited for portrait work.
A Special Low Dispersion (SLD) lens and one high refractive index SLD lens are added to correct a variety of aberrations and distortions.
"This lens is a fantastic addition to our extensive lineup of macro lenses," stated Mark Amir-Hamzeh, Sigma America president. "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."
The lens also uses Sigma's Hyper Sonic Motor (HSM) for quiet and high-speed autofocus. It uses a rounded nine-blade diaphragm to create soft blur backgrounds.
The lens features a floating focusing system that moves two different lens groups in the optical path to different positions.
Sigma said the system compensates for astigmatic aberration and spherical aberration, and provides extremely high optical performance from infinity to 1:1 macro.
A super multi-layer coating is said to reduce lens flare and ghosting, while maintaining a high contrast.
The lens is also compatible with Sigma's APO teleconverters.
