In developing a fisheye lens featuring an ultra-wide-angle and powerful fisheye distortion, Sigma has achieved a completely new level of artistic potential, combining the world's first f/1.4 aperture for consumer use with outstanding resolving power across the entire image. In terms of optical performance, the Sigma ART 15mm f/1.4 Fisheye DG DN has achieved excellent point image reproducibility and high resolution by correcting various aberrations, especially sagittal coma flare. The lens is capable of handling astrophotography, which demands particularly high-quality performance, even when wide-open. Unlike conventional fisheyes, the Sigma ART 15mm f/1.4 Fisheye DG DN is exceptionally sharp across its entire 180° angle-of-view and offers an ultra-fast f/1.4 aperture, making it perfect for a wide range of applications including astrophotography, landscapes and architecture. The expressive power of this all-new full-frame mirrorless lens opens a wealth of creative possibilities in wide-angle photography. As an interchangeable lens for full-frame cameras for consumer use.

Resolving power that overturns the conventional wisdom about fisheye lenses

The latest optical design thoroughly corrects each type of aberration. This diagonal fisheye lens has the unique expressiveness of a fisheye lens and high resolution throughout the entire image from a wide-open aperture. The performance of the lens is guaranteed by a full inspection with SIGMA's proprietary MTF measuring system.

Even wide-open, high resolution and point image reproducibility across the entire image

The lens consists of 21 elements in 15 groups, including 4 FLD and 3 SLD exclusive low- dispersion glass elements, and 2 aspherical lens elements. By correcting sagittal coma flare and other aberrations, the lens can precisely reproduce bright points of light across the whole frame even wide-open, making it ideal for astrophotography.

Diagonal fisheye lens with 180° angle of view

The powerful distortion effect, which is the appeal of fisheye lenses, allows users to enjoy expressions such as a unique perspective and emphasis on the subject at a 180° angle of view. In addition, the Sigma ART 15mm f/1.4 Fisheye DG DN is designed with the strict performance standards of the Art line. Furthermore, all lenses are inspected with Sigma's proprietary MTF measuring system. The unique descriptive power of this new fisheye lens, which combines an incredible 180° angle-of-view with very high resolution optics, delivers a level of artistic potential that exceeds other fisheye lenses.

An addition to the ART f/1.4 lineup, meticulously crafted for astrophotography

The Sigma ART 15mm f/1.4 Fisheye DG DN offers abundant functions to support astrophotography. With the introduction of this lens, SIGMA now has four f/1.4 wide-angle prime Art line lenses with functions specifically designed for astrophotography, including the 14mm, 20mm, and 24mm. In terms of both lineup and functionality, SIGMA fully supports the joy of capturing the stars.

A wealth of latest functions and excellent build quality

The Sigma ART 15mm f/1.4 Fisheye DG DN is equipped with various functions to assist shooting, including an AFL button to which preferred function can be assigned and an aperture ring, and uses a linear motor HLA (High-response Linear Actuator) as the AF actuator to enable fast, quiet, and highly accurate AF shooting. The lens is also equipped with a dust and splash resistant structure to ensure a high level of weather resistance and robustness, as well as excellent build quality that allows for long and reliable use in any environment.
