The Sigma 24mm f3.5 DG DN is a compact prime lens designed for full-frame mirrorless cameras and, at the time of testing, available in Sony e and Leica L-mounts. The 24mm f3.5 DG DN was launched in December 2020 alongside a 35mm f2 DG DN and 65mm f2 DG DN as part of Sigma’s new I series, which also includes the existing 45mm f2.8 DG DN. These four lenses are also members of Sigma’s Contemporary series, positioned below the flagship Art range, but still capable of excellent results. What differentiates the I series from other Contemporary models are their compact sizes and some interesting design ideas.

The 24mm f3.5 DG DN is weather-sealed, measures 64x49mm, weighs 225g, employs 10 elements in eight groups, has a closest focusing distance of 10.8cm, a 55mm filter thread, is supplied with a metal lens hood and two lens caps including one that’s held in place magnetically, and should be available from January 2021 at a price of $549 / 479 GBP.
