Wide 20mm f/1.4 Art Lens

This Sigma 20mm f/1.4 DG HSM Art lens mounts natively on Sony E-mount cameras and covers full-frame sensors. The optical design uses 15 elements in 11 groups including two FLD, five SLD and two aspherical elements. A Super Multi-Layer Coating reduces flare and ghosting. It suits landscape, architectural, interior and astrophotography work.

Aperture Range f/1.4 to f/16

The bright f/1.4 maximum aperture provides shallow depth of field and strong low-light performance for night skies or indoor scenes. Stopping down to f/16 extends depth of field for detailed foreground-to-background sharpness. The nine-blade rounded diaphragm produces smooth out-of-focus rendering. Diffraction will gradually soften fine detail at the smallest apertures.

Hyper Sonic AF with Manual Override

The Hyper Sonic Motor delivers fast, quiet autofocus and allows full-time manual focus override by simply turning the focus ring. A brass bayonet mount and Thermally Stable Composite barrel resist wear and temperature-related shift. The bundle adds a large lens pouch, cap keeper, blower, cleaning pen, microfibre cloth and starter cleaning kit for daily care.

Questions about this item

Will this 20mm f/1.4 lens cover the full sensor on my Sony A7 series body without vignetting?

Yes, the lens is built for Sony E-mount full-frame format, so its image circle covers the sensor completely at all apertures.

How can I verify the Hyper Sonic AF Motor and manual override are functioning correctly after mounting the lens?

Engage autofocus and listen for quiet, rapid focusing; then switch to manual focus and confirm the focus ring rotates smoothly with immediate response at any aperture from f/1.4 to f/16.

Which accessories are included in the 7PC bundle and is there anything essential I need to purchase separately?

The bundle supplies the lens, a large pouch, cap keeper, blower, cleaning pen, microfiber cloth and starter cleaning kit; no extra items are required for basic operation.
