Voigtlander 40mm f/2 Septon Aspherical Lens for Sony E

The Voigtländer SEPTON 40mm f/2 Aspherical revives the historic SEPTON concept in a compact full-frame standard prime. Its 7-element, 6-group design follows the classic Orthometar layout, with the addition of one aspherical element to improve control at f/2, while keeping the lens short and low in distortion. The result is consistent rendering across the frame in a genuinely compact form. Electronic contacts transmit Exif data and stabilisation information, allowing the manual-focus design to work seamlessly with modern digital bodies.
