Description
The Sigma 35mm f1.4 DG HSM Art Lens for Sony A is a large aperture prime lens housed in a stylish body. This lens is engineered for full frame cameras but is also compatible with APS-C sensors.
It is equipped with the latest technologies including a Hyper Sonic Motor (HSM) that ensures fast and silent autofocusing, a floating internal focusing system that delivers superb optical performance at close range shooting, and Special Low Dispersion (SLD)/”F” Low Dispersion (FLD) glass elements which assist in correcting axial and chromatic aberration.
The wide aperture performs magnificently in low-light scenarios and is also ideal for creating beautifully blurred backgrounds. This versatile prime lens is well deserving of a place in any photographer’s kit.
Sigma 35mm f1.4 DG HSM Art Lens for Sony A 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.

Wide-angle prime is designed for full-frame-format Sony A-mount cameras, however is also suitable for APS-C models where it provides a 52.5mm equivalent focal length.

Impressively 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 F Low Dispersion (FLD) element and four Special Low Dispersion (SLD) elements are featured in the optical design, and help to reduce color fringing and chromatic aberrations for improved clarity and colour accuracy.

Two aspherical elements are used to help limit distortion and spherical aberrations and also contributes to greater overall sharpness and accurate rendering.

Floating elements system helps to realise consistent optical performance throughout the focusing range, from 11.8″ to infinity.
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.
Rounded nine-blade 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 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.
