Features:

SIGMA expertise and leading-edge manufacturing technologies deliver breathtaking optical performance.
This lens features minimized aberration achieved through the latest design technology and know-how that has been accumulated by SIGMA in its lens development over many years and offers astonishing rendering performance, even at the edges, with ultra-high resolution. Whilst featuring higher resolution around the focus point, the lens offers a smooth and natural bokeh effect. Both high definition rendering without chromatic aberration and natural bokeh expression are possible, even at maximum aperture.

Leveraging our optical expertise, we have minimized sagittal coma flare for optimal capture of starry nightscapes.
Sagittal coma flare is the aberration in which a point light source appears as a streak instead of a point, and it affects large-diameter lenses in particular. By positioning aspherical lens elements toward the rear of the 24mm F1.4 DG HSM | Art, we have adjusted the angle of incidence of light for optimal power distribution. Even at wide-open aperture, you will enjoy outstanding image quality. Since streaking of point light sources toward the edges of the image is minimized, this lens is a powerful ally in photographing celestial bodies, nighttime illumination, and more.

High-contrast images with bright edges—even at wide-open aperture.
Improving efficiency at large apertures and minimizing vignetting, we have designed the lens to secure very good brightness. Even at open aperture, it ensures high-contrast images for indoor photography, astronomical photography, and when photographing blue sky.

Flare and ghosting reduction
From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.

Minimized distortion.
It is not possible to compensate for distortion that is often observed with wide-angle lenses just by changing the aperture value. Therefore, the lens development stage is vital in ensuring minimized distortion. The SIGMA 24mm F1.4 DG HSM | Art features an adjusted incidence angle of the light source from the surface of the first lens and aspherical glass elements to optimize the power layout at respective positions. This has helped minimize distortion throughout the entire image.

Rounded diaphragm
When photographing with point light sources such as electric lights or reflections on a body of water in the background, the rounded 9-blade diaphragm helps produce an attractive bokeh effect—even at large-aperture settings.
