Sigma 14-24mm F2.8 DG DN Art Leica L

Compatibility and Design

Designed specifically for full-frame Leica L-mount mirrorless cameras, the Sigma 14-24mm f/2.8 DG DN Art lens offers a versatile ultra-wide-angle zoom range with optimized size and weight. It is also compatible with APS-C format cameras, providing an equivalent focal length range of 21-36mm.

Optical Performance

• Constant f/2.8 maximum aperture throughout the zoom range allows for excellent performance in available light and greater depth of field control.
• Incorporates five Special Low Dispersion (SLD) elements and one F Low Dispersion (FLD) element to significantly reduce chromatic aberrations and color fringing, enhancing clarity and color accuracy.
• Features three aspherical elements, including a large-diameter aspherical lens, to control spherical aberrations and distortion, resulting in increased sharpness and precise image rendering.
• Super Multi-Layer Coating combined with Nano Porous Coating minimizes lens flare and ghosting more effectively than conventional coatings, producing contrast-rich and color-neutral images even in challenging lighting conditions.

Autofocus and Handling

• Equipped with a stepping autofocus motor that delivers fast, precise, and near-silent focusing, ideal for both photography and video applications.
• Full-time manual focus override is available for precise control.
• Built-in Autofocus-Lock (AFL) button can be customized to perform additional functions, expanding operational flexibility.
• Rounded 11-blade diaphragm contributes to smooth and pleasing bokeh quality.
• Front lens element features a water- and oil-repellent coating to enhance durability and performance in harsh environmental conditions.

Build and Additional Features

• Includes a built-in lens hood to protect the front element and reduce stray light causing flare.
• Rear filter holder with a fall-prevention lock allows secure attachment of gel filters at the lens mount.
• Weather-resistant construction with a brass bayonet mount improves mounting accuracy and mechanical rigidity.
• Dust- and splash-proof sealing at mount connection, manual focus ring, zoom ring, and cover connection ensures reliability in outdoor conditions.
• Supports a Front Conversion Service to convert the lens hood to a round shape, catering to multi-camera VR videography applications.

Summary

The Sigma 14-24mm F2.8 DG DN Art Leica L lens is an ultra-wide-angle zoom lens engineered for high-resolution imaging on Leica L-mount full-frame mirrorless cameras.
