Sigma Updates Lenses

Lenses incorporate weather-resistant design

The new 12-24mm contains three glass mold elements and one hybrid aspherical lens for advanced performance and compact and lightweight construction. It also features Super Multi-Layer Coating to reduce flare and ghosting, and a Hyper Sonic Motor (HSM) to ensure quiet and high-speed autofocus, while allowing full-time manual focus override. Its minimum focusing distance is 11 inches throughout the entire zoom range; its maximum magnification ratio is 1:6.4. This lens will be available at the end of April for the U.S. MSRP of $1,400.

• The APO 120-300mm F2.8 EX DG OS HSM is the successor to the APO 120-300mm F2.8 EX DG HSM that was introduced in July 2005. This telephoto lens’ new features include weather-resistant design and OS technology, and the inclusion of two FLD glass elements, along with one SLD glass element. This lens also contains Super Multi-Layer Coating, HSM, and a design that incorporates an inner focusing and inner zooming system to ensure sharp images throughout the entire zoom range. Improved optical performance provides excellent correction of sagittal coma flare, and ensures ultra-high resolution, comparable to a fixed focal length lens. When it becomes available in late February, the new 120-300mm lens’ U.S. MSRP will be $4,700.

• The APO MACRO 150mm F2.8 EX DG OS HSM is a large aperture medium telephoto macro lens. As the successor to the APO MACRO 150mm F2.8 EX DG HSM, which was first introduced in October 2004, the new version now includes the OS technology and a weather-resistant design that is for convenient outdoor use. A floating focusing system in the 150mm 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 lens also contains three SLD glass elements for correction of all aberrations, Super Multi-Layer Coating, and HSM. It will become available at the end of March for the U.S. MSRP of $1,600.
