Sigma 14mm f/1.8 DG HSM Art Series Lens - Leica L-Mount

The Sigma 14mm f/1.8 DG HSM Art Series Lens for Leica L-Mount is engineered to deliver exceptional optical performance tailored for artistic and creative applications. Here are its technical specifications:

1. Aperture Range: The lens features an aperture range from f/1.8 to f/16, offering versatility for various lighting conditions and creative depth-of-field effects.

2. Optical Design: Constructed with 11 elements in 9 groups, the lens incorporates three F Low Dispersion (FLD) elements and four Special Low Dispersion (SLD) elements. These elements effectively control chromatic aberrations and color fringing, ensuring remarkable clarity and color accuracy in images.

3. Aspherical Elements: The lens boasts four aspherical elements, including a large 80mm-diameter precision-moulded glass element at the front. These elements minimize distortion and spherical aberrations, resulting in improved sharpness and accuracy across the frame.

4. Coatings: Super Multi-Layer Coating has been applied to individual elements to reduce lens flare and ghosting, enhancing contrast and color fidelity, particularly in challenging lighting conditions.

5. Compatibility: Designed for full-frame Leica L-mount mirrorless cameras, the lens can also be used with APS-C models, providing a 21mm equivalent focal length.

6. Autofocus System: The lens features an integrated Hyper Sonic Motor (HSM) for quick and quiet autofocusing. An optimized AF algorithm ensures smooth and precise focusing performance. Full-time manual focus control is available by rotating the focus ring.

7. Construction: The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, ensuring precision and durability in various temperature conditions. The bayonet mount is made from brass for enhanced accuracy and durability. Rubber sealing is incorporated in the mount design, making it dust- and splash-resistant for reliable outdoor use.

In summary, the Sigma 14mm f/1.8 DG HSM Art Series Lens for Leica L-Mount offers outstanding optical performance, reliable construction, and versatile functionality, making it an excellent choice for astrophotography, low-light shooting, and other creative applications.
