Voigtlander's ultra-fast 21mm for Sony FE — a remarkable f/1.4 ultra-wide with electronic coupling.
The Voigtlander Nokton 21mm f/1.4 Aspherical is an extraordinary achievement — an f/1.4 lens at 21mm for Sony FE mount. This is one of the fastest ultra-wide lenses ever made for any full-frame mirrorless system. The Nokton designation and aspherical element indicate premium optics. Electronic communication with Sony bodies provides EXIF data and auto-aperture.
Optical performance is very good for the extreme specification. Sharpness is good from f/1.4 in the centre, becoming excellent by f/2.8. The f/1.4 aperture at 21mm creates an unusual combination — ultra-wide perspective with shallow depth of field that is normally impossible at this focal length. Coma control is good for astrophotography applications.
Sony FE mount with electronic communication. Filter thread is 62mm. Weight is approximately 560 grams — substantial but expected for f/1.4 at 21mm. Build quality is outstanding with precision Cosina engineering. Manual focus only with a smooth, precise helicoid. The electronic coupling provides EXIF data, aperture control, and magnification assist.
Available on the used market at moderate to premium prices. Check for smooth focus ring and clean optics. A genuinely unique lens — the combination of 21mm and f/1.4 opens creative possibilities available from no other lens. Excellent for astrophotography, creative portraits with ultra-wide distortion, and low-light street photography.
