Sigma 24mm f/1.4 DG HSM Art Lens (Sony E)

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. The 15-element-in-11-group optical design is poised to deliver consistent peripheral brightness and sharpness, even when working at the bright f/1.4 maximum aperture. 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 pair of aspherical elements, with one in the rear of the optical design, correct for sagittal coma flare, distortion, and axial chromatic aberration, while also enabling full use of the fast f/1.4 maximum aperture with maintained peripheral brightness and sharpness. 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.
