The Voigtländer Nokton 21mm F1.4 Aspherical lens for Sony E-mount that was first shown at the CP+ show in Japan back in February has now been officially unveiled.
This new wide-angle prime lens is suitable for both APS-C Sony cameras such as the Alpha A6400, and full-frame cameras like the Alpha A7R III / A7 III.
It has a built-in electronic contact for Sony E mount, so that the shooting data is recorded in the Exif information. In addition, the lens has a built-in distance encoder which supports 5-axis camera shake correction on the camera body side.
The optical configuration of the Voigtländer Nokton 21mm F1.4 Aspherical lens is comprised of 13 elements in 11 groups, with a minimum shooting distance of 25cm and a maximum shooting magnification of 1:7.5.
The aperture click switching mechanism helps to ensure that the aperture ring operation sound is not picked up during movie recording.
The Voigtländer Nokton 21mm F1.4 Aspherical is priced at ¥165,000 and will be available in June 2019.
