Sigma SIGMA Sigma Nikon F Mount Lens DG HSM Zoom Wide Angle Full Size Art SLR Dedicated 14-24mm F2.8

In order to achieve high performance throughout the entire zoom range, all the way to the periphery, in addition to 3 FLD glasses and 3 SLD glasses, 3 aspherical lenses including a large-diameter aspherical lens are used. Distortion is reduced to less than 1%* by optimizing the lens power arrangement, including a large-diameter aspherical lens on the first lens surface. While maintaining the ability to capture dots all the way to the periphery of the screen, we have ensured a rich amount of peripheral light. *At infinity The adoption of a super multi-layer coating reduces the occurrence of flare and ghosting, and achieves high-contrast depictions even when shooting against the light.
