Sigma 24mm f/1.4 DG HSM Art (Leica L-Mount)

Key Features

• Rounded nine-blade diaphragm
• Aperture Range: f/1.4 to f/16
• L-Mount Lens/Full-Frame Format
• FLD and Special Low Dispersion Elements
• Features Two Aspherical Glass Elements
• Advanced Optical Construction
• Robust Physical Design

Sigma 24mm f/1.4 DG HSM Art Series Lens - Leica L-Mount offers great optical performance and robust physical design. Super Multi-Coating has been applied to lens elements to reduce flare and ghosting for higher contrast and colour fidelity. The combination of three "F" Low Dispersion (FLD) elements and four Special Low Dispersion 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. 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. To achieve both high resolution and sharpness, along with consistent edge-to-edge illumination, this incredible lens has been designed using an advanced optical structure. 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. This prime wide-angle lens is designed for full-frame Leica L-mount mirrorless cameras, however, it can be used with APS-C models where it will deliver a 36mm equivalent focal length.

Great Features and Performance

It features a fast f/1.4 maximum aperture that is well-suited for working in a low-light environment and delivers greater control over the focus position when using shallow depth of field techniques. The rounded nine-blade diaphragm helps to produce an attractive out-of-focus quality. Featuring the integrated Hyper Sonic Motor (HSM) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM permits full-time manual focus control simply by rotating the focus ring at any moment.

Remarkable Construction

For ensured accuracy and durability, the bayonet mount is constructed from brass. Also, the included lens hood is fitted with a rubber connection for a secure fit. 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 engraved with the year of production.
