Sigma 20mm F1.4 DG DN Art

Yes, it is specifically designed for it. The lens features a dedicated heater retainer to prevent condensation during long night shoots and excellent control over sagittal coma flare, which keeps stars sharp and round across the frame.

Yes, the Manual Focus Lock (MFL) switch physically locks the focus ring in place. This is incredibly useful for long exposures or time-lapses where you need to ensure your focus point doesn't shift accidentally.

Absolutely. It includes a de-clickable aperture ring, which allows for smooth, stepless iris adjustments while recording, making it a great choice for videographers who need to control exposure transitions manually.

Yes, it has a standard 82mm filter thread on the front. Additionally, it features a rear filter holder, which gives you the flexibility to use gel filters or combine different filter types for more creative control.

The lens is built with a dust- and splash-resistant structure, making it reliable for outdoor photography. While it is durable, it is not waterproof, so you should still avoid submerging it or using it in torrential downpours without protection.

No, this lens does not feature optical image stabilization. Because it is a fast F1.4 prime lens, it is designed to be used with camera bodies that have in-body image stabilization (IBIS) or on a tripod for long exposures.
