Sigma will always be guaranteed a place in the history books as pioneers of the wide-angle zoom lens. Our advanced super wide angle technology was developed far earlier than any of our competitors.

This ultra wide angle zoom lens offers 122 degree super wide angle of view along the diagonal axis. Sigma designed and produced the first wide-angle zoom lens, the ?zoom gamma 21-35mm F3.5-4.2?, in 1979. The wide-angle zoom category didn?t even exist before this date. The market comprised only standard and telephoto zoom lenses with most people believing that wide angle zooms were impossible to develop, however Sigma?s advanced design and pioneering technology went on to prove them wrong and strongly influence subsequent product development.
Four Special Low Dispersion (SLD) glass elements are provided for effective compensation of colour aberration, which is a common problem with super-wide angle lenses. Two pieces of molded glass and three aspherical lenses, including two molded glass aspherical lens elements, offer excellent correction for linear distortion as well as all types of aberration. It is an ideal lens for Digital SLR Cameras as well as film SLR cameras.
It is easy to revert to Manual Focus by simply turning the focusing ring and overriding the AF. An inner focus system provides high performance and convenience. The non-rotating lens barrel perfectly suits the matched, built-in petal shaped lens hood.
12-24mm F4.5-5.6 EX DG lens offers a minimum focusing distance of 28cm at all focal lengths. The super-wide angle?s useful range of view offers the photographer greater freedom of expression.
This lens is equipped with a fixed Petal-type hood to obtain a superior extraneous light-blocking effect.
