The Voigtländer 40mm F2.0 SEPTON Aspherical is a standard lens that combines a compact design with high image quality for full-frame cameras with Sony E-mount and Nikon Z-mount.
SEPTON was the name given to standard lenses developed for the Bessamatic and Ultramatic SLR cameras with central shutters, which were marketed in the late 1950s and 1960s as a new photographic platform intended to replace rangefinder cameras.
SEPTON refers to a lens whose optical performance was further enhanced by adding a lens element to the six-element design of the ULTRON—which debuted in 1950 for rangefinder cameras. It is considered one of Voigtländer’s legendary lenses.
The SEPTON 40mm F2 Aspherical lenses for E-mount and Z-mount are pancake-style standard lenses whose compact design is ideally suited for mirrorless cameras.
Optimized for full-frame sensors in Sony E-mount and Nikon Z-mount cameras, they achieve an aperture of f/2 while retaining the advantages of the compact Orthometar design. This is achieved by adding an aspherical lens to the six-element Orthometar design. The Orthometar design is characterized by a short optical length and extremely low distortion.
With a total length of just 30 mm from the bayonet mount (32 mm for the Z-mount), this lens is particularly easy to carry and always within reach. The 40-mm angle of view, which can also be used as a mild wide-angle, makes it the ideal everyday lens. The minimum focusing distance of 0.3 m is excellent for tabletop and close-up shots. Both the E-mount and Z-mount versions come with a dome-shaped, screw-on metal lens hood that preserves the lens’s compact design.

The lens features electronic contacts, allowing lens data to be stored in the EXIF information of captured images. In addition, a distance encoder is built in, making the lens compatible with camera models that use 5-axis in-body image stabilization, which utilizes distance information for shake correction. Furthermore, the magnified viewfinder display is activated by turning the focus ring. The aperture ring clicks in 1/3-stop increments.
With the 40mm F2.0 SEPTON Aspherical E-Mount and Z-Mount lenses, Voigtländer is introducing two lenses that expand the versatility of modern cameras. They combine classic manual operation with the latest technology, enabling both ambitious amateur photographers and professionals to achieve impressive results.
