The Sigma 16mm f1.4 DC DN is a wide angle lens designed for mirrorless cameras with ‘cropped’ APSC sensors. Sigma offers it in Sony E and Canon EF-M mounts, as well as for the smaller Micro Four Thirds format and can convert the mount at a later date for a fee if desired. The 16mm is part of a triplet of f1.4 DC DN native mirrorless lenses: check out my Sigma 30mm f1.4 DC DN review and Sigma 56mm f1.4 DC DN review for more details. I have also filmed a video about the triplet in their most recent Canon EF-M versions below, but most of the results also apply to the other versions. Scroll below the video for a selection of sample images.
