    Highest optical performance on a new level

    Art delivers exceptionally detailed results that easily satisfy the high demands of professional photography and other high-end applications. With 17 glass elements arranged in 15 groups, including two SLD, three aspherical glass elements and the largest class double-sided aspherical glass element in SIGMA’s history, the 20mm F1.4 DG DN | Art rigorously suppresses various optical aberrations such as sagittal coma flare or image distortion to produce highly-detailed images with exceptional sharpness and accuracy from the center to the furthest corners, allowing photographers to make use of the entire field of view afforded by its ultra-wide viewing angle. This ultimate astrophotography lens is the culmination of the unparalleled manufacturing technology of SIGMA’s sole production base in Aizu, Japan, as well as the company’s know-how and experience with large-aperture wide-angle lenses, such as the SIGMA 20mm F1.4 DG HSM.

    Designed for perfect results even in the most demanding conditions

    Art with a front filter thread despite its very large F1.4 aperture and 20mm ultra-wide viewing angle. The lens also comes with a rear filter holder, allowing photographers the freedom to combine multiple filters to suit a huge variety of shooting situations for near-unlimited creative potential at an ultra-wide viewing angle—for example, using a front filter to reduce light pollution and a softening filter on the rear to take impressive photographs of nightly landscapes with star-filled skies. The new MFL (Manual Focus Lock) switch to turn off the focus ring makes it easier to concentrate on the shoot without worrying about accidentally changing the focusing distance. Further, the lens also equips a lens heater retainer, meaning that lens heaters used to prevent internal condensation as the temperature drops on longer night shoots will stay securely attached to the barrel without protruding into the image and causing unsightly vignetting. With its brilliant optical power and its full range of useful features despite its compact and lightweight body, the SIGMA 20mm F1.4 DG DN.

    Superb build quality and usability with uncompromising attention to detail

    Art safe to use during longer outdoor shoots, especially during the night. Thoughtful features such as a focus mode switch, a customizable AFL button, and an aperture ring lock switch enhance the lens usability. An aperture ring click switch can be used to turn the aperture ring click on and off, allowing photographers to enjoy the sound and feel of the click, as well as smooth aperture operation during video recording. The robust body is built from a combination of aluminum and Thermally Stable Composite (TSC), giving it a sleek finish, and the included petal-shaped lens hood is equipped with a lock mechanism to keep the hood securely fastened to the lens, and the rubberizedgrip area makes attaching and removing the hood a quick and easy process. Manufactured in Japan with an uncompromising approach towards every single detail, the SIGMA 20mm F1.4 DG DN.
