Join Krish & Sam Smith from Sigma Imaging UK as we get an exclusive first look at the two new Wide DG DN mirrorless Lenses!!

Sigma 20mm f/1.4 DG DN Art Lens for Sony E


  • E-Mount Lens/Full Frame Format
  • Aperture Range: f/1.4 to f/16
  • Two SLD Elements
  • Three Aspherical Elements
  • Super Multilayer Coating
  • Stepping AF Motor, MFL Switch
  • Rounded 11-Blade Diaphragm
  • 82mm Front Filter Thread
  • Rear Filter Holder
  • Durable Brass Bayonet Mount

An ultrawide Sony E-mount prime, the Sigma 20mm f/1.4 DG DN Art Lens offers incredible imaging performance from corner to corner, with a large maximum aperture that makes it ideal for use in low-light environments, particularly 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 functions 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 yields pin-point stars from edge to edge. Additionally, a new Manual Focus Lock (MFL) switch disables the focus ring, ensuring that focus never changes, even after hours of shooting under chilly, dark skies. The lens has also been developed to accept 82mm front filters, a rarity on ultrawide primes, and another unique feature includes a rear filter holder, which accommodates 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 notable optical performance and is ideally suited for creative and artistic applications.
  • Prime wide-angle 20mm f/1.4 lens is designed for full-frame format Sony E-mount mirrorless cameras and can also be used with APS-C models where it provides a 30mm equivalent focal length.
  • Fast f/1.4 maximum aperture is well-suited for working in low-light conditions and provides greater control over the focus position when using shallow depth of field techniques.
  • Two SLD and three aspherical elements have been incorporated within the lens design to correct for chromatic aberrations throughout the entire focusing range and to ensure exceptional clarity and contrast. This optical design also helps to control distortion and limit vignetting.
  • Employs a concave double-sided aspherical element, which provides outstanding edge-to-edge sharpness and optical performance.
  • Optimized for astrophotography, the lens offers extremely well-controlled sagittal coma flare and limits ghosting.
  • A Super Multilayer Coating has been applied to lens elements to minimize lens flare while producing contrast-rich and color-neutral imagery, even in backlit conditions.
  • Inner focus system powered by precise STM stepping motor provides high-speed autofocus and near-silent operation.
  • Optimized for astrophotography, a new MFL (Manual Focus Lock) switch disables the focus ring, ensuring that focus never changes, even after hours of shooting under chilly, dark skies.
  • Aperture ring with click switch and lock switch prevents accidental aperture changes.
  • A rounded eleven-blade diaphragm helps to produce an attractive out-of-focus quality.
  • Petal-shaped lens hood helps to 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.
  • Curved lip at the front of the lens keeps an optional lens heater from slipping in front of the lens.
  • Brass bayonet mount for ensured precision and durability.
  • Compatible with AF Assist function on select Sony E-Mount mirrorless cameras.

Sigma 24mm f/1.4 DG DN Art Lens for Sony E
  • E-Mount Lens/Full-Frame Format
  • Aperture Range: f/1.4 to f/16
  • Two FLD Elements and One SLD Elements
  • Four Aspherical Elements
  • Super Multilayer Coating
  • STM Autofocus Motor
  • Rounded 11-Blade Diaphragm
  • Brass Bayonet Mount
  • 72mm Front Filter Threads
  • Rear Filter Holder

Sporting a popular wide-angle focal length with an impressively fast aperture, this Sigma 24mm f/1.4 DG DN Art Lens delivers the professional-level of quality that Sigma's Art line is renowned for. Well-suited for landscape, architecture, street scenes, astrophotography, and more, this lens features an advanced optical and mechanical design that offers incredible edge-to-edge sharpness and overall performance. Designed for full-frame mirrorless cameras, this optic offers new features that are particularly useful for astrophotographers and nighttime landscape shooters.

Two FLD elements and one SLD element have been incorporated within the lens design to correct for chromatic aberrations throughout the entire focusing range and to ensure high image sharpness, clarity, and contrast. Additionally, four aspherical elements have been integrated into the lens's construction to eliminate distortion and suppress sagittal coma flare significantly, making this lens an ideal choice for astrophotography and nightscapes.

  • As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
  • The prime 24mm focal length offers a versatile wide-angle perspective when used on full-frame sensors, making it ideal for landscape, nature, and architectural photography. When used with a APS-C-format sensor, the lens offers a 36mm equivalent focal length.
  • Fast f/1.4 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.
  • Four aspherical elements have been integrated into the lens's construction to eliminate distortion and significantly suppress sagittal coma flare, making this lens an ideal choice for astrophotography and nightscapes.
  • Offers a standard 72mm filter thread up front, ideal for ND filters and polarizers, and also features a rear filter holder that accommodates sheet-type filter material, often used by astrophotographers for specific effects.
  • Two FLD elements and one SLD element have been incorporated within the lens design to correct for chromatic aberrations throughout the entire focusing range and to ensure high image sharpness, clarity, and contrast.
  • A Super Multilayer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
  • STM (stepping motor) provides fast and near-silent autofocus by controlling the amount of movement of the motor and optimizing the screw pitch to match the optical characteristics.
  • Manual Focus Lock (MFL) switch disables the focus ring, ensuring that focus never changes.
  • Aperture ring click switch, aperture lock switch, and hood with lock button for quick and efficient handling.
  • A rounded eleven-blade diaphragm helps to produce an attractive out-of-focus quality when shooting at large apertures.
  • NPC (Nano Porous Coating) provides a water and dust repellent coating that is incorporated into the lens's weather-resistant design.
  • High-precision, durable brass bayonet mount.
  • Compatible with AF Assist function on select Sony E-mount cameras.
