7artisans 35mm f 5 6 vs 7artisans 35mm f 1 4 iii?
Both are manual-focus 35mm primes for full frame, and both fit Sony E, Nikon Z, Canon RF and L-Mount. The difference is what they're for.
The 7Artisans 35mm f/1.4 III is the one for low light and background blur. It lets in about four stops more light than the f/5.6, and it suits environmental portraits and group shots, as I say on the portraits page.
The 7Artisans 35mm f/5.6 is a pancake built for zone-focused street photography. You set the focus distance and shoot quickly, and the deep depth of field at f/5.6 does most of the work. Go this way if you shoot in daylight and want something small to carry everywhere.
If you want one 35mm for a bit of everything, get the f/1.4 III. If you want a tiny street lens and don't mind working in good light, get the f/5.6.
