Launched July 2003


24-135mm F2.8-4.5
A zoom lens with large aperture from 24mm super-wide-angle.

Sigma introduces the new 24-135mm F2.8-4.5 zoom lens at PMA 2003. From wide angle of view more than 80°at 24mm to standard 135mm zoom lens, large aperture has been achieved. One Special Low Dispersion (SLD) glass element and 2 Aspherical Lenses effectively compensate the color aberration, as well as astigmatism, results in a high level of optical performance. At 24mm focal length this lens has a fast F2.8 maximum aperture.

This lens has a super wide range of angles of view from 84.1°to 18.2°. It incorporates an internal focusing system, which eliminates front lens rotation, allowing use of polarizing filters and Petal type hoods. The lens materials used in this new lens are lead and arsenic free ecological glass.
