The Sigma 85mm f/1.4 DG DN Art is a fast portrait prime built for full-frame Sony E-mount mirrorless cameras. It replaces the older DSLR-era 85mm Art with a smaller, lighter body designed for mirrorless, while keeping the bright f/1.4 aperture for low light and shallow depth of field. Optically it uses low dispersion, aspherical and high refractive index elements plus a Super Multi-Layer Coating to control aberrations and flare. It suits portrait, wedding and event shooters who want a fast 85mm without paying first-party prices; reviewers rate it sharp wide open with fast, quiet autofocus, though it is still a large, heavy lens and shows some vignetting and focus breathing.

Reviewers and owners rate the 85mm f/1.4 DG DN Art as one of the sharpest fast 85mm primes for Sony E-mount, with quick and quiet autofocus and attractive bokeh. Most criticism centers on its size and weight, vignetting at f/1.4 and focus breathing for video.
The Sigma 85mm f/1.4 DG DN Art is a portrait-length prime lens for full-frame Sony E-mount mirrorless systems. It is part of Sigma's Art series and has an updated optical design and a sleek profile.
The f/1.4 maximum aperture allows shooting in low light. It also gives more control over depth of field for shallow depth of field effects.
The optical layout uses low dispersion, aspherical and high refractive index elements. Its large-diameter design delivers clarity and sharpness with well-controlled distortion and aberrations. A Super Multi-Layer Coating suppresses lens flare and ghosting, which improves contrast and color fidelity in strong lighting.
