Designed for perfect results even in the most demanding conditions SIGMA's outstanding design and high-precision manufacturing capabilities made it possible to equip the SIGMA 20mm F1.4 DG DN | 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 | Art is the ultimate choice when photographing the night sky. 3. Superb build quality and usability, uncompromising attention to detail Its dust- and splash-resistant structure*1 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. Thoughtful features such as a focus mode switch, a customizable AFL*2 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 rubberized grip 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 | Art offers photographers an exceptional experience with high-end results even in the most difficult conditions, thanks to its outstanding optical performance, exceptional build quality perfect for professional use, brilliant and precise ergonomics, and a range of useful features. *1 Although this construction allows the lens to be used in light rain, it is not the same as being waterproof. *2 Only on compatible cameras.
