The lightest in its class with a bright f/1.2 maximum aperture

SIGMA's Art line has been offering new possibilities and surprise for expression, and the SIGMA 50mm f/1.2 DG DN | Art is here to break the standards. The SIGMA 50mm f/1.2 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 f/1.2 aperture. In addition, the 13-blade diaphragm allows for beautiful bokeh expressions. Focus breathing is also well-suppressed that the f/1.2 rendering can be fully utilized in video recording.

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 f/1.2. In addition, the lens construction and mechanical design have been stripped down to the bare essentials, resulting in a significantly compact and lightweight body.

Brightness of f/1.2 maximum aperture and high resolution from minimum to infinity focus

The latest optical design achieves high resolving power with each aberration thoroughly suppressed from the maximum aperture. The lens is capable of rendering details without color bleeding in any situation. In addition, the incorporated floating focus is advantageous in improving short-range performance, ensuring a stable, high-level image quality throughout the entire range from the minimum focusing distance to infinity.

Rich and beautiful bokeh without color bleeding

By correcting spherical aberration, sagittal coma flare, axial chromatic aberration, and other aberrations, the lens delivers natural bokeh images that blur smoothly and without color bleeding from the focal plane. Double-line bokeh is also suppressed, allowing users to take advantage of the mellow bokeh effect in their expression.

Designed to minimize focus breathing

Optimization of the focus group arrangement and aspherical shape significantly suppresses focus breathing. The change in angle of view due to focus shift is minimized, creating a natural-looking focus shift when recording video.

Designed to minimize flare and ghosting

Flare and ghosting, which reduce image quality, are addressed under all conditions of incident light, based on the most advanced simulation technology. High backlight resistance enables clear and sharp images under any lighting conditions.

Dual HLA incorporating a new system

A new system was developed that significantly reduces the volume while maintaining the same thrust of the HLA, which is characterized by its high driving accuracy and quietness, and is featured in each of the two focus groups. This technological innovation has realized both high-speed autofocus and a compact lens body.

Lens construction and mechanical design stripped down to the absolute minimum

Each piece of glass is made as thin as possible while employing glasses with a high refractive index and four aspherical lenses. 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 and making this mass production possible. In addition, the floating focus ensures high performance while shortening the overall length, resulting in a compact lens. In the mechanical design phase, emphasis was placed on weight reduction. Through the systematic elimination of individual components, SIGMA attained the distinction of producing the lightest lens in its class, weighing a mere 745g.

Proud to be a tool of expression, excellent build quality with SIGMA’s Art line specifications

By assembling high-precision parts made of lightweight and strong TSC and other materials, the lens has the high level of rigidity and durability of SIGMA’s Art line specifications without sacrificing portability, as well as excellent build quality that allows for long-lasting and reliable use as a photographic tool.

Various shooting assist functions

The lens is equipped with an AFL button which can be assigned to a range of functions via the menu on selected cameras. In addition to the aperture ring, the lens is equipped with an aperture ring lock switch and a click switch to turn the click on and off.

Dust and splash resistant structure and water and oil repellent coating

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.
