The Sigma 20mm f/1.4 DG DN Art Lens offers incredible imaging performance from corner to corner, with a large maximum aperture that makes it ideal for use in low-light environments, particularly under dark skies where its new features are advantageous. Always an excellent choice for landscape and architecture, this lens is equipped with newly updated functions that are especially useful for astrophotographers. Additionally, a new Manual Focus Lock (MFL) switch disables the focus ring, ensuring that focus never changes, even after hours of shooting under chilly, dark skies. The lens has also been developed to accept 82mm front filters, a rarity on ultrawide primes, and another unique feature that includes a rear filter holder, which accommodates sheet filters for various creative effects. Prime wide-angle 20mm f/1.4 lens is designed for full-frame format Leica L-mount mirrorless cameras and can also be used with APS-C models where it provides a 30mm equivalent focal length. Two SLD and three aspherical elements have been incorporated within the lens design to correct for chromatic aberrations throughout the entire focusing range and to ensure exceptional clarity and contrast. This optical design also helps to control distortion and limit vignetting. Optimized for astrophotography, the lens offers extremely well-controlled sagittal coma flare and limits ghosting. The inner focus system powered by a precise STM stepping motor provides high-speed autofocus and near-silent operation. The aperture ring with a click switch and lock switch prevents accidental aperture changes. A petal-shaped lens hood helps to reduce lens flare when working in strong lighting conditions and offers some protection to the front element of the lens. The curved lip at the front of the lens keeps an optional lens heater from slipping in front of the lens.
