Sigma 50mm f/1.4 DG HSM Art Lens (Canon EF Mount)
The Sigma 50mm f/1.4 DG HSM Art is a professional-grade standard prime lens that has become a benchmark for sharpness and optical excellence. As a flagship member of Sigma’s Global Vision Art line, this lens is engineered specifically for creative and artistic applications, offering high-resolution rendering that meets the demands of modern high-megapixel sensors.

Uncompromising Optical Engineering
Advanced Element Composition: The optical path features three Special Low Dispersion (SLD) glass elements and one molded glass aspherical element. This combination virtually eliminates axial chromatic aberration and sagittal coma flare, ensuring point-light sources (like stars) remain sharp across the entire frame.

Edge-to-Edge Brightness: Designed with a large 85.4mm diameter, the lens is built to minimize vignetting. By placing the widest elements in the front group, it maintains superior peripheral brightness even when shooting wide open at f/1.4.

Floating Internal System: A specialized floating system adjusts the gaps between glass groups during focusing. This minimizes lens movement and ensures high detail rendering from the 1.3′ minimum focus distance all the way to infinity.

Super Multi-Layer Coating: Applied to all elements to suppress flare and ghosting, this coating ensures high-contrast, color-neutral imagery even in difficult backlit environments.

Precision Focus & Performance
Hyper Sonic Motor (HSM): The integrated HSM delivers nearly silent, high-speed autofocus. An optimized AF algorithm provides smooth transitions, making it ideal for both critical portraiture and fast-paced street photography.

Full-Time Manual Override: Refine your focus instantly by simply rotating the focus ring at any time—no need to switch between AF and MF modes.

9-Blade Rounded Diaphragm: The nine rounded blades create a soft, natural, and highly aesthetic “bokeh” for beautiful subject separation and shallow depth-of-field effects.

Professional Build Quality
TSC Construction: The lens barrel is crafted from Thermally Stable Composite (TSC) material and traditional metals. This ensures the lens maintains its precision and performance despite significant temperature fluctuations.

Brass Bayonet Mount: The mount is constructed from solid brass, providing a high-degree of accuracy and long-term durability for frequent lens changes.

USB Dock Compatibility: This lens is compatible with the optional Sigma USB Dock, allowing you to update firmware and fine-tune focus parameters to your specific camera body.
