As a fast-action short normal prime, the Voigtlander 40mm f1.2 Nokton Aspherical lens has been designed specifically for Sony E-mount camera systems. The combination of a comfortable focal length and fast-action f1.2 maximum aperture encourages tactile depth of field control and benefits from low-light conditions. This lens has been manufactured to the highest optical and mechanical standards, utilising two key aspherical elements to suppress spherical aberrations and distortions. In short, this provides you with tack-sharp imagery with notable clarity and rendering accuracy. As a manual focus lens, the Voigtlander 40mm f1.2 Nokton permits working with subjects at a distance of just 50cm, as well as housing a Selective Aperture Control System to de-click the manual aperture ring.
