The perfect travel companion
With its compact design and lightweight construction, the 24mm F1.4 DG DN | Art is easy and convenient to use in any given situation. The wide viewing angle makes it easy to get everything in shot, resulting in incredible landscape vistas, characterful portraits and impressively sharp star shots at night.

Designed for the most demanding conditions
The dust and splash resistant* structure combined with a 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.
^{*Although this construction allows the lens to be used in light rain, it is not the same as being waterproof.}

Features such as a focus mode switch, a customisable 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 for smooth aperture operation during video recording.
