7artisans 14mm f 2 8 vs laowa 12mm f 2 8 zero d?
Both are manual-focus, f/2.8, full-frame prime lenses with no stabilisation, so the choice comes down to field of view and mount.
The Laowa 12mm f/2.8 Zero-D is the wider of the two. It also fits far more mounts, including Canon EF, Nikon F and Pentax K, so it's the one to pick if you have older DSLR bodies. If you want something less extreme, the 7Artisans 14mm f/2.8 is the better fit. It's also the only one of the two for L-Mount cameras.
If you shoot Sony E, Nikon Z or Canon RF, both work. Go for the Laowa for dramatic wide shots and the 7Artisans for a more natural wide view.
