Sigma 20mm f 1 4 dg dn art vs voigtl nder nokton 21mm f 1 4 aspherical?

The Sigma and the Voigtländer are close on paper. Both are fast f/1.4 wide primes for full frame, and neither has stabilisation. The big difference is focus. The Sigma 20mm f/1.4 DG DN Art autofocuses, and the Voigtländer Nokton 21mm f/1.4 Aspherical is manual focus only.

The 1mm difference in focal length barely matters. The Sigma is 20mm and the Voigtländer 21mm, so they frame almost identically.

Mounts differ too. The Sigma comes in Sony E and L-Mount, and fits a wider range of bodies, including Panasonic and Leica SL cameras. The Voigtländer comes in Sony E and Leica M.

My pick: if you want autofocus for everyday shooting, go with the Sigma. If you shoot a Leica M or enjoy slowing down and focusing by hand, the Voigtländer is the more characterful choice.
