• 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.
• Short-telephoto prime, this 105mm f1.4 lens is designed for full-frame Sony E-mount mirrorless cameras, however can also be used with APS-C models where it will provide a 157.5mm equivalent focal length.
• Impressively bright f1.4 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 F Low Dispersion (FLD) and two 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 is used to help limit distortion and spherical aberrations and also contributes to greater overall sharpness and accurate rendering.
• Large 105mm-diameter front contributes to improved peripheral illumination in order to reduce vignetting.
• 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 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) 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.
• Protective coating has been applied to the front element and is both water and oil-repellent to aid in cleaning.
• Included rotating tripod collar features an Arca-type compatible foot for seamless use atop a tripod or monopod. This collar can also be removed from the lens, and a protective cover takes its place, for more comfortable handheld use.
• Lens hood is constructed from a carbon fiber reinforced plastic to remain lightweight yet exceptionally durable.

Sigma 105mm

The Sigma 105mm f1.4 DG HSM Art Lens for Sony E-mount cameras is a short-telephoto, portrait-length prime with a bright maximum aperture that greatly benefits working in low-light conditions and also affords extensive control over depth of field for isolating subjects.

The Bokeh Master

Outstanding wide-aperture, mid-telephoto performance with f1.4 brightness at maximum aperture, the Sigma 105mm f1.4 DG HSM Art Lens for Sony E incorporates 17 optical elements in 12 groups, an uncommonly large number of elements for a prime lens. By including three FLD glass elements, two SLD glass elements, and one aspherical lens element, the optical system minimises axial chromatic aberration to deliver extremely high resolution along with ample peripheral light volume.

Like Sigma's Sports line lenses, the Sigma 105mm f1.4 DG HSM Art features a highly effective dust- and splash-proof structure with special sealing at the mount connection (with exception of the Sigma mount), manual focus ring, cover connection, and other areas, allowing photographers to work in all types of weather. In addition, the front of the lens is protected by a water- and oil-repellent coating that makes cleaning easy.

Instead of conventional ABS plastic, the exclusive lens hood features CFRP (carbon fibre reinforced plastic), a light but strong material used in the interior and exterior fittings of aircraft, among many other applications. The removable Arca-Swiss tripod socket is compatible with Arca-Swiss platform and clamps, and its exclusive protective cover makes the lens easier to carry and use when shooting hand-held.
