Key Features
Pairing an immensely versatile focal length with a bright maximum aperture, the Leica L-mount 35mm f/1.4 DG HSM Art Lens from Sigma is a wide-angle prime characterized by its advanced optical design. The combination of one F Low Dispersion (FLD) element and four Special Low Dispersion (SLD) elements help to achieve a marked reduction in chromatic aberrations, while a pair of aspherical elements, with one positioned in the rear of the lens, minimize a variety of additional distortions and aberrations. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity. Additionally, the f/1.4 maximum aperture benefits working in low-light conditions and offers increased control over depth of field for isolating subject matter.
Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override. The physical design utilizes Thermally Stable Composite material for durability in a wide Range of environments, and a brass bayonet mount also offers rigidity and mounting precision.
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.
Standard wide-angle 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 52.5mm 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.
One FLD element and four SLD elements are featured in the optical design, and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy.
Two aspherical elements reduce distortion and spherical aberrations for improved 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.
Nine-blade rounded diaphragm contributes to a smooth and pleasing bokeh quality.
The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized 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.
