2.8 maximum aperture and 9-blade rounded diaphragm
The Sigma 24-70mm f2.8 DG OS HSM Art zoom lens features a fast maximum aperture of f/2.8. When shooting at maximum aperture the lens creates wide images with a shallow depth of field, great looking bokeh thanks to a 9-bladed aperture. The fast maximum aperture also captures more light to help with low light shooting.
Four low distortion aspherical lens elements
The Sigma 24-70mm f2.8 DG OS HSM Art Lens for Canon features 4 aspherical lens elements. These elements undergo a highly precise level of polishing, producing elements thicker in the centre then on the edges. These elements effectively minimizes distortion, provides excellent peripheral brightness, beautiful circular bokeh, and edge to edge sharpness.
Optical image stabilisation
Built-in optical image stabilisation helps to reduce unwanted camera shake/movements to provide sharp pictures when zoomed in or when shooting in low light.
Three SLD glass elements
Three SLD low-dispersion glass elements are used to reduce chromatic aberrations and improve overall image quality.
Super multi-layer coating
A Super multi-layer coating on the lens greatly reduces flare, ghosting, and provides high-contrast for outstanding image quality.
New HSM autofocus motor
A new HSM AF motor provides 30% more torque than standard motors. This increase in torque helps to deliver better autofocus performance than previous art lenses.
