Sigma 14-24 mm F/2.8 AF DG DN ART Sony E

Description

The ultimate large-aperture ultra-wide-angle zoom lens

Setting a new standard of excellence for ultra-wide-angle lenses

Taking advantage of the significant advancements at the Aizu factory, SIGMA now produces ultra-high-precision, mold-based aspherical elements with diameters up to 80 mm for incorporation into its new products. This new, world-class technology promises to set a new standard of excellence in ultra-wide-angle lenses.

Exceptional image quality of the Art line

Designed for cameras of 50 megapixels or more

Designed for cameras larger than 50 megapixels and delivering top-level optical performance throughout the entire zoom range, the 14-24mm F2.8 DG HSM | Art incorporates three FLD glass elements, three SLD glass elements, and three aspherical elements, including one large-diameter aspherical element. The effective distribution of these high refractive index glass elements further enhances the corrective effect of the FLD and SLD glass. This optical system minimizes transverse chromatic aberration and other optical aberrations, resulting in exceptional high-resolution image quality.

The first element in the optical system is a large-diameter aspherical lens. Optimizing the energy distribution of this and other lens elements minimizes distortion to less than 1%. As a result, light points appear as streak-free dots from the center of the image to the edge, and the volume of light is also abundant throughout the frame. Furthermore, simulations carried out from the design stage have helped minimize flare and ghosting. In combination, these technologies provide excellent performance in this ultra-wide-angle lens.
