The Sigma 50mm f/1.4 DG DN Art lens is a high-performing prime lens for Sony E-Mount full-frame cameras. It features a revamped optical design, faster autofocusing with the High-response Linear Actuator (HLA) motor, a compact form factor, and a rounded 11-blade diaphragm for clean and consistent bokeh. The lens includes 14 elements including one SLD and three aspherical elements for sharp and accurate imagery. The lens also includes dust and splash resistance, a de-clickable aperture ring, and a customizable AFL button. The front element has a water and oil-repellent coating for protection against weather and contaminants.
