Bright F1.2 Aperture with Outstanding Optical Quality

The f/1.2 aperture provides extraordinary low-light performance and creative control over depth of field, producing images with rich contrast and vibrant colour. Its advanced optical construction effectively reduces spherical aberration, sagittal coma flare, and axial chromatic aberration. Even wide open, images remain ultra-sharp across the frame.

Sigma’s First 13-Blade Aperture

The 50mm f/1.2 is the first Sigma lens to feature a 13-blade rounded diaphragm, maintaining circular bokeh even at wide apertures. The result is beautifully smooth background blur, perfect for portraits, still life, and cinematic video work.

Optimised for Stills & Video

Engineered for modern hybrid creators, the lens minimises focus breathing and focus shift, delivering a natural look when recording video. Flare and ghosting are also suppressed, ensuring high contrast and clarity even in strong backlight or low-light environments.
