The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Voigtlander SEPTON 40mm f2 and the Voigtlander 40mm F1.4 Nokton Classic for their suitability to various photography scenarios:
Size and Weight Comparison
The weight of a lens is equally significant as its external dimensions, particularly if you intend to handhold your camera and lens combination for extended periods.

Lens Mounts
The Voigtlander SEPTON 40mm f2 has the Sony E lens mount whereas the Voigtlander 40mm F1.4 Nokton Classic has the Leica M lens mount.

Voigtlander SEPTON 40mm f2 is also available in the Nikon Z mount.

40mm but while Voigtlander SEPTON 40mm f2 has the fastest aperture of
