The new Voigtlander Nokton 40mm f1.2 is a fast, manually-controlled lens for E mount that offers camera communication for added functionality.
The new prime under the Cosina brand is the Voigtlander Nokton 40mm f1.2, a fast prime designed for the full-frame Sony FE E-mount system. At 40mm, this prime offers a versatile standard focal length that translates well to APS-C or Super 35mm for an equivalent of around 60mm.
In terms of design, the Voigtlander Nokton 40mm f1.2 is a fully manual aspherical lens, promising a smooth focus action thanks to its highly-accurate metal helicoid. Additionally, the Noktor features a switchable aperture mechanism that allows you to de-click the iris ring for smooth exposure transitions – a feature particularly useful in video use.
Despite being a manual lens, the Voigtlander Nokton 40mm f1.2 offers electrical contacts for communication with the camera body. This makes it possible to transmit EXIF lens metadata, as well as the necessary information for your camera’s In-Body Image Stabilisation (IBIS) to accurately compensate for camera shake. Also, the connection makes it possible for your camera to detect the turning of the focus wheel, automatically triggering the focus magnification assist.
With a length of 59.3mm a total weight of 420g, the Voigtlander Nokton 40mm f1.2 could be a compact alternative if you are looking for a versatile E-mount option for both full-frame and APS-C that offers a generous maximum aperture and some extra functionality.
