SIGMA 20MM F/1.4 DG DN SONY E

SIGMA 20MM F/1.4 DG DN SONY E

The Sigma 20mm f/1.4 DG DN Art lens is an ultra-wide-angle lens with a Sony E-mount that offers incredible image performance from corner to corner, with a large maximum aperture that makes it ideal for use in low-light environments, especially under dark skies, where its new features are especially useful. Always an excellent choice for landscape and architecture, this lens is equipped with newly updated features, especially useful for astrophotographers.

Combining an optical design with in-camera corrections that keep distortion under control, this lens offers an extremely well-controlled sagittal coma flare that produces sharp stars from edge to edge. Additionally, a new manual focus lock (MFL) switch deactivates the focus ring, ensuring that focus never changes, even after hours of shooting under cold, dark skies. The lens has also been developed to accept 82mm front filters, a rarity in ultra-wide prime lenses, and another unique feature includes a rear filter holder, accommodating sheet filters for various creative effects.

• As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly remarkable optical performance and is ideal for creative and artistic applications.

• The 20mm f/1.4 wide-angle lens is designed for full-frame Sony E-mount mirrorless cameras and can also be used with APS-C models where it provides a 30mm equivalent focal length.

• The fast f/1.4 maximum aperture is ideal for working in low-light conditions and provides greater control over the focus position when using shallow depth-of-field techniques.

• Two SLD elements and three aspherical elements have been incorporated into the lens design to correct chromatic aberrations throughout the focus range and ensure exceptional clarity and contrast. This optical design also helps control distortion and limit vignetting.

• Employs a double-sided concave aspherical element, which provides exceptional edge-to-edge sharpness and optical performance.

• Optimized for astrophotography, the lens offers an extremely well-controlled sagittal coma flare and limits ghosting.

• A super multi-layer coating has been applied to the lens elements to minimize lens flare while producing images rich in contrast and neutral in color, even in backlit conditions.

• The internal focusing system driven by a precise STM stepping motor provides high-speed autofocus and near-silent operation.

• Optimized for astrophotography, a new MFL (manual focus lock) switch deactivates the focus ring, ensuring that focus never changes, even after hours of shooting under cold, dark skies.

• The aperture ring with click switch and lock switch prevents accidental aperture changes.

• An eleven-blade rounded diaphragm helps produce an attractive blur quality.

• The petal-shaped hood helps reduce lens flare when working in strong lighting conditions and offers some protection to the front element of the lens.

• 82mm front filter threads and rear filter holder for sheet-type filters.

• The curved edge at the front of the lens prevents an optional lens heater from sliding in front of the lens.

• Brass bayonet mount to ensure precision and durability.

• Compatible with the AF assist function on some Sony E-mount mirrorless cameras.
