Voigtlander lenses have fixed focal lengths without autofocus and are also known for making all-metal manual focus lenses that offer durable construction and sharp images. The Nokton 21mm f/1.4 Aspherical lens is another of the Voigtlander lenses, and it provides a unique focal length paired with a very wide maximum aperture.
The Nokton 21mm f/1.4 Aspherical lens has quite an interesting focal length, offering a wide angle of view, but one that won’t bring too much distortion with it, and with that f/1.4 maximum aperture, the lens is quite versatile. It also has impressive features such as:
- 13 elements in 11 groups
- Two aspherical elements for reduced distortion and increased sharpness
- Three partial dispersion elements for reduced chromatic aberrations and increased clarity
- Floating element system for high image quality throughout focusing range
- 12-blade diaphragm for particularly smooth bokeh
- De-clickable aperture for video work
- Electronic contacts for EXIF data transfer and use of advanced camera functions, such as focus magnification
