Sigma 50mm f/1.4 DG HSM Art Lens for Leica L

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 normal-length lens is designed for full-frame Leica L-mount mirrorless cameras, however it can also be used with APS-C models where it will provide a 75mm equivalent focal length.

Bright 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.

Three Special Low Dispersion (SLD) elements are featured in the optical design, and help to reduce colour fringing and chromatic aberrations for improved clarity and colour accuracy.

One aspherical element reduces distortion and spherical aberrations for improved sharpness and accurate rendering.

A Super Multi-Layer 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.

Nine-blade rounded diaphragm contributes to a smooth and pleasing bokeh quality.

The integrated HSM (Hyper Sonic Motor) realises quick and quiet autofocusing, which is further complemented by an optimised AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.

The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations.

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.
