The 24-105mm F/4 DG OS HSM Lens from Sigma is a wide-angle to medium telephoto zoom lens with a constant f/4 aperture. It is designed for both full frame and crop sensor Canon DSLR cameras.

The lens integrates three aspherical elements into its construction as well as two SLD and two FLD glass elements to help minimize aberration, field curvature, and distortions throughout the zoom range as well as provide greater image sharpness while avoiding reduced peripheral brightness. Super Multi-Layer Coating has also been applied to lens elements to reduce surface reflections, lens flare, and ghosting to produce images with higher contrast and color fidelity.

The barrel of the lens is constructed from a Thermally Stable Composite (TSC) material that offers minimal thermal shrinkage and exceptional hardness. For autofocus, a Hyper Sonic Motor (HSM) delivers high speed focus with minimal noise, making it well suited for continuous shooting and video recording.
