"We, Sigma Corporation, are the pioneer of the wide angle zoom. In 1979, we introduced the first wide angle zoom lens, "Zoom Gamma 21-35 F3.5-4". Since then, we've been leading the development of the wide angle zoom lenses. (1994/ 18-35mm F3.5-4.5, 1999/ 17-35mm F2.8-4, 2001/ 15-30mm F3.5-4.5 2003/ 12-24mm F4.5-5.6) We hope the customers can enjoy the improved performance."
