Voigtl nder nokton 21mm f 1 4 aspherical vs ttartisan 21mm f 1 5 asph?

Both are manual-focus, unstabilised 21mm primes for full frame, and they frame the same. The Voigtländer is the faster one at f/1.4 against f/1.5, which is a small gap in practice. Choose by mount rather than by spec.

• On Sony E or Leica M, take the Voigtländer Nokton 21mm f/1.4. It has the wider aperture, and it fits a Sony a7 III or a Leica M11.
• On Nikon Z or Canon RF, the TTArtisan 21mm f/1.5 ASPH is the one to get. It fits a Nikon Z6 III or a Canon EOS R6 Mark II, and the Voigtländer doesn't.

If you're mainly shooting Sony E, I'd still look at the Voigtländer first. Its aperture is the only real edge it has over the TTArtisan.
