Fred Miranda (Click here) tested the new Voigtländer 40mm f/2.0 FE lens and concluded:

Overall, the 40mm f/2 Septon is not about record breaking sharpness or minimal compromises. Its strengths lie in its compact size, lightweight handling, excellent center sharpness, good control of chromatic aberration, and the character in the way it draws. For photographers seeking a compact normal lens for street, travel, or general-purpose use on Sony E or Nikon Z bodies, the Septon offers a capable balance of performance and portability, with enough personality to make images feel distinct without introducing major optical trade-offs.
