Pairing an immensely versatile focal length with a bright maximum aperture, the Sony E-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 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.
