Sigma 50mm F1.4 DG DN Art Lens Sony E-Mount The New Benchmark in Standard Prime Lenses The Sigma 50mm F1.4 DG DN Art is a next-generation standard prime lens designed specifically for full-frame Sony E-mount mirrorless cameras. Part of Sigmas renowned Art line, it offers outstanding optical performance, ultra-fast autofocus, and a compact, robust design, making it an exceptional choice for professionals and enthusiasts alike. Ideal for portraits, weddings, street, family, landscapes, and video, this versatile lens delivers the expressive power and detail that photographers demand from a true flagship optic. Exceptional Optical Performance Building on the legacy of the original Sigma 50mm F1.4 Art, this redesigned DG DN version achieves even higher levels of image quality, particularly at the edges of the frame. 14 elements in 11 groups, including 1 SLD (Special Low Dispersion) and 3 aspherical elements. Suppresses sagittal coma flare, astigmatism, and field curvature for unparalleled clarity. Smooth, natural bokeh with 11 rounded diaphragm blades for beautifully rendered backgrounds. Ultra-wide F1.4 aperture delivers razor-sharp results in low light, with stunning shallow depth of field for subject isolation. Perfect for shooting wide open, the lens produces edge-to-edge sharpness and beautifully smooth out-of-focus areas, making it a go-to lens for expressive photography. New High-Speed Autofocus System The 50mm F1.4 DG DN Art is the first Sigma Art DG DN lens to feature the HLA (High-response Linear Actuator) motor, providing: Ultra-fast, near-silent AF with pinpoint accuracy. Reliable subject tracking even with moving subjects. Significant performance improvements for both stills and video. Thanks to this new design, Sigma engineers were able to reduce the focusing group to a single double-sided aspherical element, resulting in a lighter, more responsive system that benefits both AF speed and optical performance. Robust Yet Compact Design Engineered to feel perfectly balanced on modern mirrorless cameras, the 50mm F1.4 DG DN Art is slimmer and lighter than its DSLR predecessor, weighing just 670g.
