The Sony E-mount 105mm f/1.4 DG HSM Art Lens from Sigma is a short-telephoto, portrait-length prime distinguished by its bright maximum aperture and advanced optical layout. As part of the Art line of lenses, this lens is also designed for high-resolution rendering and utilizes FLD and SLD glass to control chromatic aberrations and color fringing for notable clarity. Additionally, a rounded nine-blade diaphragm contributes to a pleasing bokeh quality. For working atop a tripod, a removable tripod collar is also included and features an Arca-type compatible foot for wide mounting compatibility. Short-telephoto prime, this 105mm f/1.4 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 157.5mm equivalent focal length. Three F Low Dispersion (FLD) and two Special Low Dispersion (SLD) elements are featured in the optical design and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy. The integrated HSM realizes quick and quiets 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. 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.

The 24mm f/1.4 DG HSM Lens is a member of the highly regarded Art line of Sigma‘s Global Vision Series and is characterized by its advanced optical construction and robust physical design. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity. This focusing motor also enables full-time manual focus override at any time just by rotating the focus ring for refined manual control.  Additionally, nine rounded diaphragm blades contribute to pleasing out-of-focus quality when working with shallow depth of field techniques. 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 Fast 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. 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. 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 outside of the lens barrel is also engraved with the year of production.
