Sigma 56mm f/1.4 DC DN Contemporary, RF Mount Lens

The Sigma 56mm f/1.4 DC DN Contemporaray Lens - RF Mount is a standard prime lens from Sigma with an f/1.4 aperture and a 55mm filter size for the Canon RF mount. It weighs 280g and is suited to landscape and travel use.

Technical Details

Sigma 56mm f/1.4 DC DN Contemporary Lens for RF Mount. The 56mm f/1.4 DC DN, a particularly streamlined portrait-length prime, forms part of Sigma's Contemporary lens series, designed specifically for Canon RF-M-mount mirrorless cameras.

Its defining feature is the bright f/1.4 maximum aperture, ideal for challenging lighting conditions and offering enhanced control over depth of field for subject isolation and selective focus techniques. The lens's optical design incorporates two aspherical elements and one SLD element, effectively reducing both spherical and chromatic aberrations to deliver superior sharpness and clarity.

A super multilayer coating is also applied to combat flare and ghosting, ensuring greater contrast and colour accuracy in intense lighting conditions. The lens is further enhanced by a stepping AF motor, perfect for both photo and video applications due to its fast, accurate, and virtually silent performance.

Key Features

• Bright f/1.4 maximum aperture
• Two aspherical elements and one SLD element
• Super multilayer coating
• Stepping AF motor
• Dust and splash resistant mount design

As part of the Contemporary line within Sigma's Global Vision series, this lens is designed to achieve a balance between convenience and performance, and meshes a compact, lightweight build and versatile handling with notable optical attributes.

Portrait-length prime is designed for APS-C-format Canon RF-mount mirrorless cameras and provides an 89.6mm 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.

Optical Design

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

A super multilayered coating has been applied to lens elements in order to minimise 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 to ensure accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust and splash resistant.
