Sigma just announced two new full-frame prime lenses for mirrorless cameras: the Sigma 24mm F2 DG DN Contemporary and the 90mm F2.8 DG DN Contemporary lenses. Both new Sigma lenses will be available in L-mount and Sony E-mount versions and will sell for $639 each.

The Sigma 24mm F2 DG DN Contemporary and the 90mm F2.8 DG DN Contemporary lenses will go on sale at the end of September 2021. The two new lenses are part of Sigma’s “I Series” line, which are distinguished by their all-metal bodies, metal internal parts and metal lens hoods. All I Series lenses feature a manual aperture ring and knurled surfaces for a better grip.
