An Art level 20mm F1.4. The ultimate lens for astrophotography.
The full-frame SIGMA 20mm F1.4 DG DN | Art for Sony E-Mount is a mirrorless version of the SIGMA 20mm F1.4 DG HSM | Art; the one and only lens with its unique specification of maximum aperture of 1.4 and an ultra-wide angle of 20mm.
This lens offers photographers overwhelming optical performance and unlimited potential for ultra wide-angle creativity at a compact physical size. The exceptional F1.4 brightness and the breathtaking sharpness across the entire image even at maximum aperture make this lens the ultimate choice for astrophotography. In nightly darkness and focused to infinity, the 20mm F1.4 DG DN | Art captures stars in the sky as clear, precise pinpoints of light.
State-of-the-art optical design and the large, high-precision double-sided aspheric glass front element made it possible to add a front filter thread without any compromises regarding optical performance or size.
The addition of other invaluable features such as a rear filter holder and a variety of useful switches further increases the creative possibilities and easy usability of the lens. Its incredible sharpness and very bright aperture, coupled with the compact body and thoughtful features, make the SIGMA 20mm F1.4 DG DN | Art the ultimate lens for astrophotography and an ideal companion for any photographically demanding situation.
The SIGMA 20mm F1.4 DG DN | Art for Sony E-Mount Mirrorless camera 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 | Art, the SIGMA 14mm F1.8 DG HSM | Art and the SIGMA 14-24mm F2.8 DG DN | Art.
When the MFL switch is set to “LOCK”, the focus ring operation will be disabled. This is to prevent the focus ring from accidentally being moved, which would cause out-of-focus images.
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, sharp photographs of nightly landscapes with star-filled skies.
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 | Art is the ultimate choice when photographing the night sky.
Its dust- and splash-resistant structure and the water- and oil-repellent coating on the front glass element make the SIGMA 20mm F1.4 DG DN | Art safe to use during longer outdoor shoots, especially during the night.
This Sigma 20mm f/1.4 DG DN Art Lens for Sony E-Mount comes with a full Australian warranty from Sigma Australia.
