Professional Overview
Sigma's 24-70mm f/2.8 DG DN II Art lens represents a significant evolution in professional zoom optics, delivering superior rendering performance in a body that's 15% shorter and 10% lighter than its predecessor. Designed specifically for full-frame mirrorless systems (Sony E-mount/L-mount), this flagship zoom combines cutting-edge optical engineering with practical innovations like a customizable aperture ring and dual HLA linear motors. The lens maintains exceptional edge-to-edge sharpness even at f/2.8, with improved close-focus capabilities (6.7" MFD) and virtually no focus breathing - making it equally suited for high-resolution stills and 8K video production.
