Sigma 56mm F1.4 DC DN, Contemporary, Leica L-Mount

Sigma 56mm F1.4 DC DN | Contemporary

The ultra-sleek portrait-length 56mm f/1.4 DC DN is part of the Sigma Contemporary series of lenses. The lens features a bright f/1.4 maximum aperture, which is suitable for working in difficult lighting conditions and allows for greater control over depth of field for separating subjects and working with selective focus techniques. The optical design uses two aspherical elements and one SLD element, which help 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 for greater contrast and color accuracy when working in bright light. The optics are complemented by a step-up AF motor, which is suitable for both stills and video shooting due to its fast, precise and near-silent operation.

Part of the Sigma Global Vision series' Contemporary line, this lens is designed to balance comfort and performance, with a compact, lightweight body and versatile handling with notable optical performance.

• The bright f/1.4 maximum aperture is great for low light, and also allows for better control over depth of field for selective focus effects.


• One Special Low Dispersion (SLD) element reduces color fringing and chromatic aberrations for greater clarity and color accuracy.


• Two aspherical elements are used to limit distortion and spherical aberrations, and also contribute to greater overall sharpness and accurate rendering.


• The lens elements have been coated with a super multi-layer coating to reduce lens flare and ghosting and produce contrasty and neutral color images even in backlit conditions.


• The step-up AF motor is beneficial to both photographers and videographers due to its fast, accurate, and near-silent operation.


• The rounded nine-blade diaphragm ensures smooth and pleasing bokeh quality.


• The bayonet mount is made of brass for precision and durability. Additionally, the mounting design features a rubber seal to make it dust and splash resistant.
