A classic portrait-length lens updated for full-frame Leica L-mount mirrorless systems, the Sigma 85mm f/1.4 DG DN is an Art-series prime characterized by its advanced and updated optical design, sleek profile, and bright design. The f/1.4 maximum aperture enables working in low-light conditions and also provides increased control over depth of field for achieving shallow depth of field effects. The optical layout incorporates a series of low dispersion, aspherical, and high refractive index elements and its large diameter design achieves a notable degree of clarity and sharpness with well-controlled distortion and aberrations. Also, a Super Multi-Layer Coating enhances image quality by suppressing lens flare and ghosting for improved contrast and color fidelity in strong lighting conditions.
As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
Portrait-length lens is designed for full-frame L-mount mirrorless cameras but can also be used with APS-C models where it provides a 127.5mm equivalent focal length.
Bright f/1.4 maximum aperture is particularly well-suited for working in available light conditions and provides extensive control over depth of field for isolating subject matter with selective focus.
Five Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing for improved clarity and color accuracy.
One aspherical element and four high refractive index glass elements control spherical aberrations and distortion for increased sharpness and accurate rendering.
