Available exclusively for L-Mount and Sony E-Mount, it continues Sigma’s tradition of crafting premium fast-aperture Art lenses that photographers and videographers can rely on.

Perfect for portraits, weddings, street, landscapes, events, and cinematic video, this lens delivers remarkable sharpness, expressive bokeh, and exceptional versatility, making it a must-have for any professional or enthusiast’s kit.

Exceptional Optical Performance

Building on the reputation of the original Sigma 50mm F1.4 Art, this new DG DN version is purpose-built for mirrorless cameras and delivers superior results across the frame.

• 14 elements in 11 groups, including 1 SLD (Special Low Dispersion) and 3 aspherical elements.

• Suppresses chromatic aberrations, sagittal coma flare, astigmatism, and field curvature.

• Edge-to-edge sharpness, even at the maximum F1.4 aperture.

• 11-blade rounded diaphragm for beautifully smooth, rounded bokeh.

• Ultra-wide F1.4 aperture for exceptional low-light performance and shallow depth of field.

Whether you’re shooting in natural light, capturing moody portraits, or working in controlled studio setups, this lens delivers consistently high-quality, expressive results.

Ultra-Fast & Precise Autofocus

The HLA (High-response Linear Actuator) autofocus motor ensures rapid, accurate, and near-silent focusing – perfect for both stills and video.

• Smooth subject tracking, even with fast-moving subjects.

• Lightweight single double-sided aspherical focus element improves both AF speed and optical performance.

• Supports DMF (Direct Manual Focus) and AF+MF functionality for precision control.

Compact & Robust Professional Design

Despite its wide aperture and advanced optical design, the Sigma 50mm F1.4 DG DN Art weighs just 670g, making it an excellent match for today’s lightweight mirrorless systems.

• Dust- and splash-resistant structure with a rubber seal at the mount.

• Water- and oil-repellent coating on the front element.

• Thermally Stable Composite (TSC) outer barrel ensures performance remains consistent across temperatures.

• Balanced handling with a compact form factor, perfect for on-the-go use.

Advanced Features for Photographers & Videographers

The lens is equipped with a professional feature set designed to support both stills and video workflows:

• Manual Aperture Ring with lock switch.

• Aperture Click Switch – choose stepped or clickless aperture control (ideal for video).

• Customisable AFL Button for assigning functions (depending on camera model).

• Focus Mode Switch for quick AF/MF changes.

• Robust Lens Hood with lock mechanism and rubberised grip for secure handling.
