Dpreview shared these images of the new Voigtlander 21mm f/1.4 FE lens mounted on Sony A7rIII:
Optical construction comprises 13 elements in 11 groups, with at least one aspherical element (Cosina is being a little vague, for now, on the exact optical formulation). Like the Nokton 50mm, there are 12 aperture blades, and electrical contacts communicate focal length and aperture to the camera.
The Nokton 21mm F1.4 is a fairly large lens, with a 62mm filter thread. For video use, the aperture dial can be ‘de-clicked’ for smooth stepless control. Minimum focus is 0.25m (about 10 inches).
This is an exciting addition to the FE lens lineup! Fast and compact….perfect for my hiking tours!
