• Fits both full-frame and APS-C mirrorless cameras
• New optical formula with 5 SLD and 1 Aspherical element
• Lightweight And Compact 
• Dust and Splash Proof Construction

85mm f/1.4 is a specification almost synonymous with a portrait lens. With the Art line lenses, SIGMA pursues the highest optical performance possible and has devoted the latest optical design technologies, as well as the production technologies of the Aizu factory, SIGMA's only production site, to the development of these lenses. The result is a detailed image critical for portrait photography that is achieved at a level that will satisfy both professional and advanced amateur photographers.

In addition to five SLD (Special Low Dispersion) elements and one aspherical lens, the 85mm f/1.4 DG DN Art has incorporated the latest high refractive index glass, which works to thoroughly correct aberrations that cannot be handled by the correction functionality on the camera side. With a particular emphasis given to the correction of axial chromatic aberration, users will enjoy sharp images with no color bleeding, all the way up to the maximum aperture of F1.4.

The high resolving power that covers the entire image from the center to the edges ensures sharpness of the area in focus, and coupled with the significant bokeh effect produced by the F-value of 1.4 brings out the users’ subject in an evocative way.

The numerous rounds of ray-trace simulation, as well as repeated real-world testing, have given the 85mm f/1.4 DG DN Art its ability to minimize ghosting, ensuring clear, sharp images even when shooting in backlit conditions.

With the ability to shoot from the maximum aperture of f/1.4 without worrying about image quality, users can focus on the camera operations to realize their artistic expressions, such as the adjustment of exposure and depth of field. This new lens indeed delivers a level of optical performance truly worthy of the name of 85mm f/1.4 Art.

A full range of functionalities and an excellent build quality
This compact lens is packed with a range of functionalities that will satisfy both professional and advanced amateur photographers.

The 85mm f/1.4 DG DN Art has newly introduced an “Iris ring lock switch.” This prevents from unintended movement of the iris ring during shooting, allowing users to devote their attention to the creation of their image. The “Focus Mode Switch” on the lens body and the “AFL button*” that allows various functions to be assigned from a camera body will also assist users’ shooting.
