A Premium Lens
Designed for Full Frame Cameras
Sigma 24-105mm F/4 DG OS HSM Lens - A wide-angle to
medium telephoto zoom lens featuring a constant f/4 aperture. Sigma has
engineered lenses for both full frame and crop sensors for Canon, Nikon,
Sigma and Sony 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.
