Sigma 14-24mm f/2.8 DG HSM Art-Series Lens for Nikon F-Mount
Designed for High-Resolution Cameras
- Designed to team up with 50-megapixel-plus cameras for top-level optical performance throughout the zoom range.
- Incorporates three FLD glass elements, three SLD glass elements, and three aspherical lens elements, including one large-diameter aspherical element.
- Effective distribution of high-refractive-index glass elements enhances the corrective effect of the FLD and SLD glass.
- Optical system minimizes transverse chromatic aberration and other optical aberrations, resulting in outstanding high-resolution image quality.
Minimized Distortion and Aberrations
- The first element in the optical system is a large-diameter aspherical lens.
- Optimized power distribution of lens elements minimizes distortion to 1% or lower.
- Points of light appear as points without streaking from the center of the image to the edge.
- Abundant light volume throughout the frame.
- Simulations performed from the design stage onward help minimize flare and ghosting.
- Combined technologies ensure excellent ultra-wide-angle performance.
Versatile Wide-Angle with Bright Design
- Wide-angle zoom lens for FX-format Nikon F-mount cameras.
- Suitable for DX models, providing a 21-36mm equivalent focal length range.
- Fast f/2.8 constant maximum aperture for low-light conditions and greater depth of field control.
Sophisticated Optical Design
- Series of low dispersion and aspherical elements:
- Reduces chromatic and spherical aberrations.
- Achieves high sharpness, clarity, and color accuracy.
- Super Multi-Layer Coating:
- Suppresses lens flare and ghosting.
- Produces contrast-rich and color-neutral imagery.
Advanced Focusing Performance
