A 20mm F1.4 at art level.
The ultimate Lens for astrophotography.
1. Highest optical performance at a new level
2. Developed for perfect results even under the most difficult conditions
3. First-class build quality and ease of use with uncompromising attention to detail

Outstanding optical quality and a host of useful features - the ultimate astrophotography Lens from the pioneer of the 20mm F1.4
The F1.4 series represents the SIGMA Art product line, which strives for the highest optical performance and expressive imaging characteristics. Designed for full frame, the SIGMA 20mm F1.4 DG DN | Art is the mirrorless version of the SIGMA 20mm F1.4 DG HSM | Art; the only Lens* that combines the large aperture of F1.4 with an ultra wide-angle focal length of 20mm. The lens delivers stunning optical performance and opens up unlimited possibilities for photographers to take creative wide-angle shots, while remaining absolutely compact.

Its unusually high speed of F1.4 and the breathtaking sharpness throughout the entire image circle, even wide open, make it the first choice for astrophotography. In the dark at night and focused to infinity, the 20mm F1.4 DG DN | Art reproduces the stars as clear, precise points of light.

State-of-the-art optical design and the large, high-precision, double-sided aspherical front lens make a front filter thread possible without having to compromise on optical performance or dimensions. Additional practical features such as a rear filter holder and a range of useful switches expand the creative possibilities and make working with this Lens easier. Its incredible sharpness and large aperture, combined with compact dimensions and clever equipment details, make the SIGMA 20mm F1.4 DG DN | Art the ultimate lens for astrophotography and an ideal companion in challenging shooting situations.
* As an AF Lens for mirrorless system cameras that covers the image circle of the 35 mm format (as of August 2022, according to SIGMA)

1.
Highest optical performance at a new level
The SIGMA 20mm F1.4 DG DN | Art delivers exceptionally detailed results that effortlessly meet even the high demands of professional photography and other high-end applications.
With 17 glass lenses in 15 groups, including two SLD elements, three aspherical elements and the largest double-sided aspherical glass lens in SIGMA's history, the 20mm F1.4 DG DN | Art successfully suppresses various aberrations such as sagittal coma and distortion. As a result, the photographer obtains images with the finest details and outstanding sharpness from the center to the corners. This means that the entire field of view captured by the ultra-wide-angle lens can be used without restrictions. This ultimate lens for astrophotography is a culmination of the unrivaled manufacturing technology of SIGMA's only production facility in Aizu, Japan, and the company's know-how and experience with fast wide-angle lenses, such as the SIGMA 20mm F1.4 DG HSM | Art, the SIGMA 14mm F1.8 DG HSM | Art and the SIGMA 14-24mm F2.8 DG DN | Art.

2.
Developed for perfect results even under the most difficult conditions
SIGMA's special expertise in development and high-precision manufacturing made it possible to build the SIGMA 20mm F1.4 DG DN | Art with a front filter thread despite its large aperture of F1.4 and the very wide angle of view due to the focal length of 20mm. The Lens also has a rear filter holder, which gives photographers the freedom to combine several filters.

This allows an almost unlimited creative potential of extreme wide-angle shots to be realized in a wide variety of situations. For example, you can use a front filter to reduce light pollution and a soft-focus filter in the filter holder for impressive photos of nocturnal landscapes under a star-studded sky. With the new MFL switch (for "Manual Focus Lock"), you can deactivate the focus ring to concentrate purely on the photo without having to worry about accidentally adjusting the distance.

To prevent the lenses from fogging up in the cold of the night, you can use a lens warmer for which SIGMA has provided a special device. This ensures that the warming collar remains securely in the correct position on the barrel and cannot cause vignetting. With its brilliant optical performance and wide range of useful features in a compact size and light weight, the SIGMA 20mm F1.4 DG DN | Art is the best choice for night sky photography.

3.
First-class build quality and ease of use with uncompromising attention to detail
Thanks to its dust- and splash-proof construction*1 and the water- and oil-repellent coating on the front lens, the SIGMA 20mm F1.4 DG DN | Art is suitable for outdoor use at night. Intelligent equipment details such as a focus mode switch, a configurable AFL*2 button and an aperture ring lock switch further enhance user-friendliness. Another switch can be used to turn the aperture ring click-stop on and off, allowing you to switch between tactile and audible aperture operation with click-stop and smooth and silent aperture adjustment when shooting video. The robust lens body is made from a combination of aluminum and TSC (Thermally Stable Composite) plastic material with similar thermal expansion, giving the lens a sleek, elegant finish. The supplied tulip-shaped lens hood snaps securely onto the lens and its rubberized grip area makes it quick and easy to attach and remove. The SIGMA 20mm F1.4 DG DN | Art is manufactured in Japan with uncompromising attention to the smallest details and promises photographers high-end results even under the most difficult conditions. The outstanding optical performance and the special manufacturing quality, which make the lens ideal for professional applications, as well as perfect ergonomics and a wide range of useful features contribute to this.

Sigma's 70-200 f/2.8 is a strong competitor to lenses from Sony and Panasonic. The attractive price of €1,699 RRP makes the Sigma a worthwhile alternative, especially in comparison to the 70-200 2.8 from Panasonic and Sony's new G-Master, which is significantly more expensive.
