Sigma’s 28-105mm f/2.8 Art Combines Fast Aperture and Long Reach
Sigma announced the 28-105mm f/2.8 DG DN Art lens for Sony E and Leica L mount systems. It combines the speed of the much loved 24-70mm f/2.8 lens type with the more versatile focal range of the 24-105mm f/4 in one, sacrificing a bit of range at the wide end to maintain the f/2.8 aperture.
