## Long description

The SIGMA 20mm F1.4 DG DN \| Art for Sony E is an ultra-wide prime lens combining a very large F1.4 aperture with a 20mm focal length to deliver high-resolution, edge-to-edge sharpness for landscapes, astrophotography and wide-angle scenes. Its optical construction of 17 elements in 15 groups, including SLD and aspherical glass elements and a large double-sided aspherical element, reduces aberrations and distortion while maintaining compact dimensions and a usable feature set such as a front filter thread and rear filter holder.
Advantages
This lens offers exceptional low-light performance and shallow depth-of-field capability thanks to the F1.4 aperture, plus excellent corner-to-corner sharpness through an advanced optical design that suppresses sagittal coma flare and other aberrations. It is built with dust- and splash-resistant construction and a water- and oil-repellent front coating for reliable outdoor use. Usability features include a focus mode switch, customizable AFL button, aperture ring with click on/off, manual focus lock, lens heater retainer and a locking petal-shaped hood.

How to use
Mount the lens on a compatible Sony E-mount camera and set the focus mode using the focus mode switch for AF or MF as required. Use the aperture ring to select the desired f-stop; switch the aperture ring click on/off depending on whether you need tactile detents (photography) or smooth control (video). Attach front and/or rear filters as needed for exposure control or special effects. Engage the manual focus lock (MFL) to fix focus for long exposures or time-lapse work. If shooting at night, use the built-in Lens Heater Retainer and an appropriate lens heater to reduce dew formation.
Usage recommendations
For astrophotography, shoot at wide open aperture (f/1.4) with careful focusing and use the rear filter holder only when necessary; enable the MFL for long exposures. For landscapes, stop down to f/5.6–f/11 for maximum depth of field and sharpness. Keep the front element clean and use the water- and oil-repellent coating and dust/splash-resistant design during extended outdoor sessions.
