Sigma 20mm f/1.4 DG DN ART Sony FE

The Sigma 20mm F1.4 DG DN Art is a fast prime lens that delivers exceptional optical performance in the most demanding situations. This makes it the ideal choice for astrophotography, thanks to its sharpness from corner to corner, even at full aperture.

The lens system of the Sigma 20mm f/1.4 DG DN ART features two SLD elements, three aspherical glass elements, and a large double-sided aspherical glass element. This allows the lens to suppress optical aberrations such as flares and distortion with ease, enabling it to meet the high demands of the professional photographer.

When shooting conditions require a great deal of attention or could affect your images, it's reassuring to have a lens that helps you out. The lens is equipped with a Manual Focus Lock switch, which lets you easily disable the focus ring so you don't have to worry about the focus distance shifting — ideal when you've got the night sky perfectly sharp. In addition, the lens design makes it straightforward to attach a lens heater, which prevents internal condensation when shooting in cold conditions, such as during a clear night out in the field.

The Sigma 20mm F1.4 DG DN Art features a robust body with a dust- and splash-proof construction. The front glass element also has a water- and oil-repellent coating. The housing is made from aluminium combined with Thermally Stable Composite (TSC), giving the lens its refined finish. Practical features such as the focus mode switch, customisable AFL button, and aperture ring lock are all easy to operate, making the Sigma 20mm F1.4 DG DN Art a highly user-friendly yet premium lens for the discerning photographer.
