The Canon EF-mount 24-105mm f/4 DG OS HSM from Sigma is an Art-series zoom covering a useful wide-angle to the short-telephoto range. Featuring a constant f/4 maximum aperture, this lens strikes an ideal balance between a portable form factor along with a bright enough design for working in available lighting conditions. Complementing this design, an Optical Stabilizer helps to minimize the appearance of camera shakes throughout the zoom range for sharper handheld shooting. This lens is also distinguished by its advanced optical layout, which includes a series of low-dispersion elements and three aspherical elements. These specialized elements reduce chromatic and spherical aberrations throughout the zoom range in order to realize a high degree of sharpness and clarity. As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.

Standard zoom is designed for full-frame Canon EF-mount cameras, however, can also be used with APS-C models where it provides a 38.4-168mm equivalent focal length range. Two F Low Dispersion (FLD) elements and two Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy. A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions. The optical Stabilizer system minimizes the appearance of camera shake to benefit from making sharper imagery when shooting handheld. Constructed using a Thermally Stable Composite (TSC) material for greater precision and use in wide temperature variations. Additionally, a brass bayonet affords improved mounting accuracy and rigidity.
