Sigma Press Release

A compact zoom lens with large aperture from 24mm super-wide-angle

Sigma Corporation is pleased to announce the launch of the new 24-60mm F2.8 EX DG lens.

From super-wide-angle of 24mm this lens has a very compact design as well as a large-aperture. By effective arrangement of Special Low Dispersion (SLD) and aspherical glass elements, this lens has compact dimensions of 83.6mm (3.3in.) maximum diameter, and 84.5mm (3.3in.) length. It is capable of taking pictures from a close distance, minimum focusing distance is 38cm(15.0in.) at all focal lengths, and has a maximum magnification ratio of 1:5.8. Two Special Low Dispersion (SLD) glass elements are provided for effective compensation of color aberration, which is a common problem with super-wide angle lenses. One piece of Glass Mold Aspherical and three pieces of Hybrid Aspherical, total four pieces of aspherical lenses offer excellent correction for distortion as well as all types of aberration. The new lens coating reduces flare and ghost, which is a common problem of digital cameras and also creates an optimum color balance.


The design concept of this lens is especially suitable for the characteristics of Digital SLR Cameras. The high performance inner focus system is particularly suitable for using circular polarizing filters and a petal-type hood as the front of the lens does not rotate. This lens is also equipped with Zoom Lock Switch that eliminates "Zoom Creep". This remarkably compact high performance zoom lens is ideally suited for traveling.
