Sigma 35mm f/1.4 DG HSM Art Lens for E Mount

The Sigma 35mm f/1.4 DG HSM Art Lens for E Mount is a wide-angle prime lens dedicated for E-mount cameras. The Sigma 35mm f/1.4 DG HSM Art Lens for E Mount is a part of the Art line of lenses, meaning it focuses on image quality and rendering while utilizing one FLD and four SLD glass elements. These help to control chromatic aberrations and color fringing for notable clarity. The Sigma 35mm f/1.4 DG HSM Art Lens for E Mount also has four aspherical elements, including the front large-diameter precision molded glass element. These contribute to reducing distortion and spherical aberrations which in turn improves sharpness and accuracy. 

Additionally, a Super Multi-Layer Coating has been applied to individual elements to suppress lens flare and ghosting for greater contrast when working in strong lighting. Well-suited to astrophotography and low-light outdoor shooting, this lens presents a unique blend of a broad perspective and fast, flexible performance.

Complementing the optical performance is an equally adept Hyper Sonic Motor, which provides fast, smooth, and near-silent autofocus performance. This focusing motor also enables full-time manual focus override at any time just by rotating the focus ring for refined manual control. The lens barrel is constructed using a Thermally Stable Composite material, which supports working in a wide variety of temperatures and conditions, and the lens mount is constructed from brass for long-term durability and mounting accuracy.

Key Features

• 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 Sony E-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.
