The Voigtländer lens 21mm / 1:1.4 Nokton, which was introduced in June, has a wide angle and very fast light, and its optical design has been redesigned for Sony E-Mount. A total of 13 elements are installed in eleven groups, including two lens elements with aspherical surfaces and a "floating element". The aperture consists of 12 lamellas and can be optionally unclicked.
Focusing is manual, but the lens has electrical contacts so that image information can be stored in the EXIF data. The closest focusing distance is 25cm. The lens weighs 560g, the filter diameter is 62mm.
The Voigtländer 21mm / 1:1,4 Nokton aspherical E-Mount is available from the end of June for 1.399 Euro.
