  • 84mm (35mm Equivalent)
  • Aperture Range: f/1.4 to f/16
  • One SLD Element, Two Aspherical Elements

The Sigma 56mm f1.4 DC DN Contemporary Lens for L-Mount is designed for use with APS-C-format L-mount mirrorless cameras. The lens is characterized by its bright f/1.4 maximum aperture, which suits working in difficult lighting conditions and also offers improved control over depth of field for isolating subjects and working with selective focus techniques.

The optical design utilizes two aspherical elements and one SLD element, which help to reduce both spherical and chromatic aberrations for greater sharpness and clarity. A Super Multi-Layer Coating has also been applied to suppress flare and ghosting in order to achieve more contrast and colour accuracy when working in strong lighting conditions. Complementing the optics is a stepping AF motor, which suits both photo and video applications due to its quick, precise, and near-silent performance.

 

Key Features of the Sigma 56mm f1.4 DC DN Contemporary Lens for L-Mount

  • Designed to achieve a balance between convenience and performance. Meshing a compact, lightweight build and versatile handling with notable optical attributes.
  • Portrait-length prime is designed for APS-C-format Leica L-mount mirrorless cameras and provides an 84mm equivalent focal length.
  • Bright f/1.4 maximum aperture excels in low-light conditions and also affords increased control over depth of field for achieving selective focus effects.
  • One Special Low Dispersion (SLD) element reduces colour fringing and chromatic aberrations in order to achieve greater clarity and colour accuracy.
  • Two aspherical elements are used to limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering.
  • A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and colour-neutral imagery, even in backlit conditions.
  • A stepping AF motor benefits both photographers and videographers with its fast, precise, and near-silent performance.
  • Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
  • The bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.

 

Compact lens construction with image quality rivalling SIGMA's Art line.

To achieve such a compact construction, lens design is considered based on the capabilities of the camera body function to correct* peripheral light amount and distortion. Moreover, axial colour aberration, which is difficult to eliminate by image processing, is efficiently corrected by incorporating an SLD glass element.

Designed to minimize flare and ghosting

From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.

Rounded 9-blade diaphragm

The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

 

Part of Sigma's high-performance Contemporary line, featuring SIGMA’s latest technologies

While retaining the compact, lightweight, and outstanding image quality concepts of the Contemporary line, thanks to SIGMA’s leading-edge technology, this lens provides the amount of bokeh and admirable brightness expected from F1.4 lenses even in the mid-tele range. This addition completes the large aperture series comprised of portable wide-angle, standard, and telephoto lenses.

Smooth AF ideal for video shooting

The combination of optical design for video AF and use of the stepping motor enables smooth and quiet autofocus. This lens is also compatible with the Sony E-mount Fast Hybrid AF, achieving precise AF tracking. By using the face recognition or eye AF functions of cameras, focus will continuously be on the face or the eye even if the subject moves during the shoot.

High-precision, rugged brass bayonet mount with dust- and splash-proof construction

The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens. It also features a special sealing to make the lens an excellent choice in a wide variety of conditions.
