Overview

*Expected delivery Fall 2019*

Outstanding wide-aperture, mid-telephoto performance with F1.4 brightness atmaximum aperture, this lens incorporates 17 optical elements in 12 groups, an uncommonly largenumber of elements for a prime lens. By including three FLD glass elements, two SLD glass elements,and one aspherical lens element, the optical system minimizes axial chromatic aberration to deliverextremely high resolution along with ample peripheral light volume.

Like SIGMAs Sports line lenses, the 105mm F1.4 DG HSM | Art features a highly effective dust- and splash-proof structure withspecial sealing at the mount connection (with exeption of the Sigma mount), manual focus ring, coverconnection, and other areas, allowing photographers to work in alltypes of weather. In addition, the front of the lens is protected by awater- and oil-repellent coating that makes cleaning easy.

Instead of conventional ABS plastic, the exclusive lens hood features CFRP (carbon fiber reinforcedplastic), a light but strong material used in the interior and exterior fittings of aircraft, among manyother applications. The removable Arca-Swiss tripod socket is compatible with Arca-Swiss platform and clamps, and its exclusive protective cover makes the lens easier to carry and use when shootinghand-held.
