Sigma 16mm f 1 4 dc dn contemporary vs yongnuo yn16mm f 1 8s da dsm?

Both are 16mm primes for APS-C, and on a Sony E body both give a 24mm-equivalent view. The difference is light. The Sigma opens to f/1.4, so it gathers more light and gives a shallower background, which suits low light and night streets. The Yongnuo's f/1.8 is still fast, and it's a sensible choice if you mainly shoot in daylight.

The Sigma also covers far more mounts: Sony E, Fujifilm X, Micro Four Thirds, L-Mount, Canon RF and Nikon Z. The Yongnuo is Sony E only. If you're on Sony and want the faster aperture, I'd pick the Sigma 16mm f/1.4. If you're on Sony and daylight is your main thing, the Yongnuo YN16mm f/1.8 is a solid pick.
