Sigma DN Series
Designed for Micro Four Thirds, E-mount systems
• The Sigma 19mm F2.8 EX DN is a wide angle lens with the equivalent angle of view of a 38mm (35mm equivalent focal length) on the Micro Four Thirds system and 28.5mm (35mm equivalent focal length) on the E-mount system. It has a minimum focusing distance of 7.9 inches and a maximum magnification ratio of 1:7.4. Three glass mold aspherical lenses provide excellent correction for distortion, color aberration and field curvature, and an inner focusing system corrects the fluctuation of aberration to maintain image quality regardless of the focal length. The 19mm F2.8 EX DN lens features a rounded, seven-blade diaphragm, which ensures smooth rendering of the out-of-focus areas of the image.
