Sigma has released a slew of new lenses – four to be exact, namely a 14mm f/1.8 DG HSM Art, 135mm f/1.8 DG HSM Art, 24-70mm f/2.8 DG HSM OS Art and a 100-400mm f/5-6.3 DG HSM OS Contemporary.
According to Sigma, the 14mm is the first full-frame ultra-wide with an f/1.8 aperture and incorporates a large aspherical front element, three FLD (“F” Low Dispersion) elements and four SLD (Special Low Dispersion) elements which all work together to reduce distortion, produce better edge-to-edge sharpness and reduce chromatic aberration.
