Sigma AF 20mm F1.4 DG DN | Art Lens

Sigma AF 20mm F1.4 DG DN | Art Lens (414965). The SIGMA 20mm F1.4 DG DN | Art is a wide-angle, ultra-wide-aperture prime that is perfect for astrophotography. Available in L-Mount and Sony E-mount, it delivers outstanding Art-line optical quality and offers a range of advanced features. As well as being very well-suited to astro, the 20mmF1.4 is an ideal optic for landscapes, interiors and a range of other wide-angle applications.

Weighing in at just 635g, the lens is significantly lighter and more portable than Sigma’s existing 20mm F1.4,and introduces a number of important features including a manual aperture ring with de-click and lock functionality, a front filter thread and rear filter holder, a Lens Heater Retainer to hold a heat strip in position, and an all-new Manual Focus Lock switch to fully deactivate the focus ring.

The optical performance of the lens is exceptional, with ultra-sharp results across the entire frame even at F1.4, and very well controlled sagittal coma flare – essential for astrophotography. The bright aperture is perfect for night sky landscapes, as well as for hand-held low-light shooting and for achieving a shallow depth-of-field.

This superb image quality, compact form-factor and advanced feature-set, combined with a beautifully constructed body, make for a versatile, high-performance optic that will enable photographers to unleash their creative potential and start achieving wide-angle images with impact.
