Sigma has introduced two new large-aperture wideangle primes for full-frame mirrorless cameras, in the shape of the Sigma 20mm F1.4 DG DN | Art and Sigma 24mm F1.4 DG DN | Art.

Both lenses are are considerably smaller and lighter than their older DSLR counterparts, while gaining an array of additional controls, as previously seen on the firm’s 85mm F1.4 DG DN | Art. Specifically, both lenses include an aperture ring that can be set to either clicked or smooth operation. In addition to aperture settings at one-third stop intervals, this ring has an A position which passes aperture control to a dial on the camera body, and a switch on the side of the barrel can lock the aperture either into, or out of the A position.
Both lenses also boast physical AF/MF switches and AF-stop buttons. One notable new feature is a focus lock switch which completely inactivates the manual focus ring. This allows astrophotographers to set the focus to infinity, and then lock it in place. Read More...
