SIGMA 50MM F1.2 DG DN - Sony E Mount

Description

SIGMA’s focus with this lens is on the descriptive power of the widest aperture, and portability for high performance 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. Lens construction and mechanical design have been perfected, resulting in a significantly compact and lightweight body. The lens is 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. The superb Art F1.2, which will transform everything they capture and even their photographic experience into something extra special.

Highest descriptive power to take advantage of F1.2 brightness
The SIGMA 50mm F1.2 DG DN | Art has been designed with an emphasis on high resolution from the maximum aperture to the full focus range and large, beautiful bokeh expression. The contrast between the sharpness of the focus surface and the melting bokeh effect creates a three-dimensional effect thanks to its F1.2 aperture. SIGMA’s first 13-blade diaphragm allows for beautiful round bokeh expressions. Focus breathing is well-suppressed so the F1.2 rendering can be fully utilized in video recording. The lens is capable of rendering details without color bleeding in any situation. By incorporated floating focus, Sigma improved short-range performance, ensuring a stable, high-level image quality throughout the entire range from the minimum focusing distance to infinity. By correcting spherical aberration, sagittal coma flare, axial chromatic aberration, and other aberrations, the lens delivers natural bokeh images that blur smoothly and without colour bleeding from the focal plane. Double-line bokeh is also suppressed, allowing users to take advantage of the mellow bokeh effect in their expression. Optimization of the focus group arrangement and aspherical shape significantly suppresses focus breathing. Change in angle of view due to focus shift is minimized, creating a natural-looking focus shift when recording video. Flare and ghosting, are addressed under all conditions of incident light. High backlight resistance enables clear and sharp images under any lighting conditions.

Lightest weight lens body in its class suitable for a wide range of applications

HLA volume is greatly reduced while maintaining the same thrust, which is characterized by its high driving accuracy and quietness. The high level of production technology at SIGMA’s only manufacturing base, the Aizu factory, provides the exacting precision necessary for processing these thin glass elements. The floating focus ensures high performance while shortening the overall length, resulting in a compact lens. Through the systematic elimination of individual components, SIGMA attained the distinction of producing the lightest lens in its class, weighing a mere 745g / 26.3oz. 

A wealth of functions for professional use and excellent build quality
The SIGMA 50mm F1.2 DG DN | Art is designed with high functionality and reliability to meet the stringent demands of professionals, as well as excellent build quality for long-lasting, reliable use. The lens is equipped with an AFL button which can be assigned to a range of functions via the menu on selected cameras. The lens is equipped with an aperture ring and a aperture ring lock switch and a click switch to turn the click on and off. In addition to a dust and splash resistant structure, the front element of the lens features a water and oil repellent coating, allowing photographers to shoot without concerns even in harsh outdoor environments.
