Excuse me while I hit the rewind button for a moment… It’s October 2019 and I’m enjoying some very happy days reviewing the Sigma 16mm f/1.4 DC DN | C with a Canon EOS M50 camera. A variety of other APS-C format versions of this lens were available at the time, as well a Micro Four Thirds option. Further down the line, the supporting cast grew, spreading the joy to a grand range of L-mount, Sony E, Canon EF-M and RF-S, Fujifilm X, Nikon Z DX and Micro Four Thirds mount options. That covers most of the mirrorless crop-sensor bases and then some.
I was so impressed with the Sigma 16mm at the time that I gave it a 5-star rating and one of our coveted gold awards. Even so, it wasn’t entirely perfect, as it lacked any weather-seals and it wasn’t particularly compact or lightweight, which was only to be expected from a fast f/1.4 prime at the time. Enter the new replacement.
