Class-leading optical performance

In addition to five SLD elements and one aspherical element, the Sigma 85mm F1.4 DG DN Art Lens has incorporated the latest high-refractive-index glass, which works to correct aberrations that cannot be effectively handled by in-camera correction. With a particular emphasis given to the elimination of axial chromatic aberration, you will enjoy sharp images with no colour bleeding all the way up to the maximum aperture of F1.4. The high resolving power across the entire image from the centre to the edges of the frame ensures exceptional sharpness of the in-focus area, and coupled with a very shallow depth-of-field it’s easy to separate the subject from the background for captivating, high-impact portraits.

Exceptionally lightweight and compact

The Sigma 85mm F1.4 DG DN Art lens weighs in at 630g with a filter size of 77mm and a body length of 94.1mm. Designed exclusively for mirrorless cameras, it combines a very large lens diameter, superb optical performance and a lightweight and compact body. The AF system employs a stepping motor that is optimised for both phase detect and contrast AF. Not only does this provide a smooth shooting experience only possible on a mirrorless camera (such as face/eye AF), but it has reduced the size of the lens body thanks to a much smaller focus element. This lens is the perfect ultra-wide aperture 85mm lens for day to day shooting, or to carry around all day at a wedding, without worrying about being weighed down.

Superb build quality with impressive features

This compact lens is packed with a range of advanced functionalities that make it well-suited to professional use by both photographers and film makers.
The Sigma 85mm F1.4 DG DN | Art has a newly introduced iris ring lock switch, which allows users to lock the iris ring either at auto, or between apertures F1.4-F16. This prevents unintended movement of the ring from auto to manual, or vice versa, during shooting so you can focus on creating your shot. There is a Focus Mode Switch on the lens barrel, and an AFL button that allows various functions to be assigned from the camera body. Furthermore, in addition to the dust- and splash-proof structure, the Sigma 85mm F1.4 DG DN Art Lens uses materials such as aluminum and TSC (Thermally Stable Composite) to achieve superb Art-line build quality, but with weight kept to a minimum.
