Sigma 14-24mm f/2.8 DG DN Art Lens for Leica L-Mount

Overview

• 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.
• Created for full-frame Leica L-mount mirrorless cameras, this wide-angle zoom is designed to deliver excellent image quality while optimizing size and weight. It is also suitable for APS-C models where it provides a 21-36mm equivalent focal length range.
• Constant f/2.8 maximum aperture is well-suited for working in available light conditions and provides greater control over the depth of field.
• Five Special Low Dispersion (SLD) elements and one F Low Dispersion (FLD) element markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy.
• Three aspherical elements, including a large-diameter aspherical lens, control spherical aberrations, and distortion for increased sharpness and accurate rendering.
• A Super Multi-Layer Coating combined with a NanoPorous Coating has been applied to lens elements in order to minimize lens flare and ghosting to a greater degree than conventional anti-reflective coatings. The combination of these coatings produces contrast-rich and color-neutral imagery and helps to make the lens even more effective in backlit conditions.
• A stepping AF motor benefits both photographers and videographers with its fast, precise, and near-silent performance. Full-time manual focus control can also be selected.
• Built-in Autofocus-Lock (AFL) button can be assigned additional functions that widen the range of operations available on the lens.
• A rounded eleven-blade diaphragm contributes to a smooth and pleasing bokeh quality.
• The front lens element has been treated with a water- and oil-repellent coating to benefit from working in harsh environmental conditions.
• The included rear filter holder is equipped with a fall-prevention lock for attaching and securing gel filters along with the lens mount.
• Weather-resistant construction with a brass bayonet that affords improved mounting accuracy and rigidity.
