Voigtländer is launching the SEPTON 40mm F2 Aspherical E-mount and SEPTON 40mm F2 Aspherical Z-mount, standard lenses designed exclusively for full-frame Sony E-mount and Nikon Z-mount cameras.
SEPTON was the name given to the standard lenses developed for the lens-shutter SLRs Bessamatic and Ultramatic, marketed in the late 1950s and 1960s as a new photographic platform to replace rangefinder cameras. SEPTON is a lens that further enhanced optical performance by adding one lens element to the six-element configuration of the ULTRON, which debuted in 1950 for rangefinder cameras. It is recognised as one of Voigtländer's legendary lenses.
The SEPTON 40mm F2 Aspherical E-mount and Z-mount are pancake-style standard lenses offering compactness suited to mirrorless cameras. Optimised for full-frame Sony E-mount and Nikon Z-mount sensors, it achieves an F2 aperture while retaining the benefits of the compact Orthometar type. This is accomplished by adding one aspherical lens to the six-element Orthometar type. The Orthometar type is characterised by its short optical length and extremely low distortion.
With a compact overall length of 30mm from the mount flange (32mm for Z-mount), it minimises the hassle of carrying and retrieving from a bag. Its 40mm angle of view, suitable for use as a wide-angle lens, makes it ideal as an everyday lens. The minimum focusing distance of 0.3m also makes it excellent for table photography. Both E-mount and Z-mount versions include a dome-shaped metal screw-on hood that preserves the lens's compactness.
