Sigma 85mm f/1.4 DG DN Art Lens for Leica L

A classic portrait-length lens updated for full-frame Leica L-mount mirrorless systems, the Sigma 85mm f/1.4 DG DN is an Art-series prime characterized by its advanced and updated optical design, sleek profile, and bright design.

• 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.
• Portrait-length lens is designed for full-frame L-mount mirrorless cameras but can also be used with APS-C models where it provides a 127.5mm equivalent focal length.
• Bright f/1.4 maximum aperture is particularly well-suited for working in available light conditions and provides extensive control over depth of field for isolating subject matter with selective focus.
• Five Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing for improved clarity and color accuracy.
• One aspherical element and four high refractive index glass elements control spherical aberrations and distortion for increased 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 color-neutral imagery, even in backlit conditions.
• Integrated stepping motor realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance.
• Manual aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications. Additionally, a dedicated aperture ring lock switch can also be employed to prevent accidental shifting of the aperture setting.
• Built-in Autofocus-Lock (AFL) button which can be assigned additional functions widens the range of operations available on the lens.
• Rounded eleven-blade diaphragm contributes to a smooth and pleasing bokeh quality.
• Weather-resistant construction with a brass bayonet that affords improved mounting accuracy and rigidity.
• This lens is compatible with the optional Sigma UD-11 USB Dock for fine-tuning different lens characteristics and updating its firmware.
