7artisans 50mm f 0 95 vs voigtl nder nokton 50mm f 1 2?
Both are manual-focus 50mm primes for APS-C cameras, and both frame like roughly 75mm on full frame. The difference is the aperture and the mounts.
The 7Artisans 50mm f/0.95 is the faster lens. Its f/0.9 gives about the depth of field of f/1.4 on Sony E, Fujifilm X, or Nikon Z. It also comes in several mounts, so it's the better pick if you might switch systems.
The Voigtländer Nokton 50mm f/1.2 is made for Fujifilm X only. It's the choice if you already shoot Fuji and want a lens built for that system, with f/1.2 giving about the depth of field of f/1.8.
For people, a 50mm is a good place to start, so see portraits as well.
