An optical formula offering unrivalled performance at F1.4

To reconcile outstanding wide-aperture performance with an F1.4 maximum aperture medium-telephoto focal length, this lens contains 17 lenses in 12 groups - an unusually high number of elements in a fixed focal length. By including 3 FLD glass elements, 2 SLD glass elements and 1 aspherical element, the optical system minimizes axial chromatic aberration to deliver extremely high resolution. The in-focus area is sharp, while the out-of-focus area boasts a beautiful bokeh effect with very natural colors, making this lens an ideal choice for portraiture. The optical system also minimizes sagittal coma flare.

Exceptional peripheral brightness

The most effective way to let in the maximum amount of light is to maximize the diameter of the front lens. With its large 105mm filter diameter, the SIGMA 105mm F1.4 DG HSM Art offers a significantly greater volume of peripheral light than other lenses in its class.

Truly professional features

Like SIGMA's Sports line lenses, the 105mm F1.4 DG HSM features a highly effective dust and water repellent construction with special seals on the mount*, focus ring, connection cover and other areas, enabling photographers to work in all kinds of weather conditions. What's more, the front element has a water-repellent treatment that allows water to drain off easily and grease to adhere, making the lens easy to care for. High-speed, high-precision autofocus helps photographers react in an instant for unprecedented shots.

* The SIGMA mount does not have a gasket, which is present on compatible SIGMA cameras.

Intuitive ergonomics for ease of use

Instead of conventional ABS thermoplastic polymer, the exclusive sunshield is made of carbon-fiber-reinforced polymer, a lightweight yet robust material. The removable foot collar is compatible with the Arca-Swiss quick-release standard, and its exclusive protective ribbon makes the lens easier to carry and use for freehand photography.

Available for full-frame sensor cameras with Sony E mount

The Sony E-mount version of this lens is compatible with Sony hybrid cameras, while featuring the same optical formula as the other mounts. The lens is also compatible with Sony's continuous AF mode. Sigma plans to offer a Sony E-mount version of every full-frame fixed-focal lens currently available in the Art line, from 14mm to 135mm.
