 Sigma 24-60mm f2.8 EX DG lens launch: Already announced at the PMA 2004 we inform you with the real launch of this new Sigma lens. From super-wide-angle of 24mm the Sigma 24-60mm f2.8 EX DG 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 maximum diameter, and 84.5mm length. It is capable of taking pictures from a close distance, minimum focusing distance is 38cm 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.

 Sigma EX DG lens - Digital concept
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 travelling. The release date for Sigma and Canon mounts is June 2004, for Nikon the middle of June 2004. For Konica Minolta and Pentax no specific dates are mentioned yet.
