The Sigma 105mm f/1.4 DG AF HSM Art lens with Canon EF, Sony E, Nikon F and Sigma mounts is a member of Sigma's Art family characterized by its advanced optical construction and robust design. The combination of low-dispersion FLD and SLD elements helps to reduce chromatic aberrations, while a pair of aspherical elements, one of which is at the rear of the lens, further minimizes distortion and aberration. The optical design of 17 elements in 12 groups delivers consistent peripheral brightness and sharpness, even at a maximum aperture of f/1.4. A Super Multi coating has been applied to the lens elements to reduce flare and ghosting.
It has an efficient hypersonic motor that is fast, smooth and quiet. Nine rounded diaphragm blades contribute to a pleasing out-of-focus quality with shallow depth of field.

The Sigma 105mm f/1.4 DG HSM short telephoto portrait lens distinguished by its bright maximum aperture and advanced optical layout. The fast f/1.4 design greatly benefits low-light work and also offers ample control over depth of field for subject isolation and selective focus work. As part of the Art line of lenses, this lens is also designed for high resolution, and uses FLD and SLD glass to control chromatic aberrations and colour fringing for remarkable clarity. The multi-layer coating also enhances image quality by suppressing flare and ghosting to improve contrast and colour fidelity in brightly lit conditions. In addition, a rounded nine-bladed diaphragm contributes to a pleasing bokeh quality.
To complement the imaging capabilities, the lens features a hypersonic motor (HSM) that produces fast, smooth and quiet autofocus performance with full-time manual focus override. The physical design uses Thermally Stable Composite material for durability in a wide range of environments, and a brass bayonet mount also offers rigidity and mounting precision. For working on a tripod, a removable tripod collar is also included that features an Arca-type compatible foot for wide mounting compatibility.
This Sigma 105mm f/1.4 DG HSM lens is called a "bokeh master" by the manufacturer, which highlights its character for portraits, and its diaphragm has been created in a rounded shape to create an attractive effect in many situations. Like all Sigma ART series lenses, it is dust- and splash-resistant thanks to highly effective sealing on the mount.
