Description and Reviews

Key Take-Aways:

The Sigma 50mm f/1.2 DG DN Art is a large-aperture standard prime that balances an f/1.2 aperture with a relatively compact 745g design, making it the lightest lens of its kind. Professional reviews praise its excellent sharpness even wide open, attractive bokeh, fast autofocus, and competitive pricing, while noting some vignetting, longitudinal chromatic aberration, and that it remains larger than f/1.4 alternatives. As of Sep 14 2025, user sentiment is strongly positive, with many photographers highlighting it as a practical way to access f/1.2 performance without the bulk or price of first-party options.

From Sigma:

UNVEILING ANOTHER Sigma ART LINE F1.2 LENS. ELEVATING PHOTOGRAPHIC MASTERY BEYOND CONVENTIONAL LIMITS.

The lightest in its class* ― Bright F1.2 maximum aperture and the highest level of descriptive power from Sigma’s Art line

Sigma’s Art line has been offering new possibilities and surprise for expression, and now the Sigma 50mm F1.2 DG DN | Art is here to break the standards. Sigma’s focus with this lens is on the descriptive power that is perfectly usable from the widest aperture, and on portability that allows the high performance to be demonstrated in any field. In terms of image rendition, Sigma achieved high resolving power from the maximum aperture throughout the entire focus range, while also enriching the beauty of the large bokeh effect at F1.2. In addition, the lens construction and mechanical design have been stripped down to the bare essentials, resulting in a significantly compact and lightweight body.

The lens is also equipped with a full range of functions suitable for professional use, including high-precision AF using the latest HLA (High-response Linear Actuator) that reduces volume while maintaining the same thrust. We hope users will enjoy the superb Art F1.2, which will transform everything they capture and even their photographic experience into something extra special.
