Sigma 85mm f/1.4 DG HSM Art Lens for Nikon F

The Sigma 85mm f/1.4 DG HSM Art is a full-frame compatible portrait prime lens mounting via Nikon F, belonging to Sigma’s Art line which prioritizes maximum optical performance and image quality. The f/1.4 maximum aperture delivers pronounced background separation and strong low-light capability, making it a natural fit for portraiture, editorial, and event work. The optical design incorporates Special Low Dispersion (SLD) and anomalous dispersion glass elements to control chromatic aberration and maintain sharpness and contrast across the frame. Sigma’s HSM (Hypersonic Motor) autofocus system provides fast and quiet operation with full-time manual focus override. As a third-party lens, autofocus performance and compatibility may vary across Nikon F-mount body generations, and fine-tuning via Sigma’s USB Dock is available for focus calibration.
