With a no-holds-barred approach to design, the 105mm f/1.4 DG HSM Art Lens from Sigma is a short-telephoto, portrait-length prime distinguished by its bright maximum aperture and advanced optical layout. The fast f/1.4 design greatly benefits working in low-light conditions and also affords extensive control over depth of field for isolating subjects and working with selective focus. As part of the Art line of lenses, this lens is also designed for high-resolution rendering, and utilizes FLD and SLD glass to control chromatic aberrations and color fringing for notable clarity. A Super Multi-Layer Coating also enhances image quality by suppressing lens flare and ghosting for improved contrast and color fidelity in strong lighting conditions. Additionally, a rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet auto focus performance with full-time manual focus override. The physical design utilizes 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 atop a tripod, a removable tripod collar is also included and features an Arca-type compatible foot for wide mounting compatibility.
