Sigma ART 50-100mm f/1.8 DC HSM for Nikon
Setting a new benchmark for image quality, the 50-100mm F1.8 DC HSM Art delivers the highest level of optical performance to increase your expressive power. Incorporating FLD glass, SLD glass, and high-refractive index, high-dispersion glass minimizes aberrations. To minimize axial and transverse chromatic aberration, this lens features an optimal arrangement of three FLD (“F” Low Dispersion) glass elements, one SLD (Special Low Dispersion) glass element, three high-refractive index SLD glass elements, and one high-refractive index, high-dispersion glass element. By including one or more low-dispersion element in every element group, this lens ensures outstanding image quality throughout the zoom and focal range. Video Inspired Inner Focus and Inner Zoom Rings Designed with videography in mind the inner focus and inner zoom rings do not change the length of the lens and allow for zoom ring operation without shifting focus.
