The Sigma 24-60mm f/2.8 lens has a very compact design for a lens with this large an aperture. By effective arrangement of Special Low Dispersion (SLD) and aspherical glass elements, this lens has compact dimensions of 3.29" maximum diameter, and 33.2" length. And with other advanced features like IF (Internal Focusing), two SLD (Special Low Dispersion) elements, 4 aspherical elements, Zoom Lock switch, this lens is a high performance zoom lens, ideally suited for everyday or traveling use. The improved DG lens coating reduces flare and ghosting, which is a common problem of digital cameras, and also creates an optimum colour balance. And the wide angle range of this lens also makes it ideal for use with digital SLR cameras, providing a focal zoom range of approximately 36 to 90mm.
