Voigtlander Nokton 21mm F1.4 Aspherical Lens
Product Gallery
Product Overview
Voigtlander NOKTON 21mm F1.4 Aspherical is a large-aperture, wide-angle manual-focus lens optimized for Sony mirrorless or Leica rangefinder cameras. With an angle of view just over 90 degrees and an ultra-bright f/1.4 maximum aperture, the NOKTON 21mm F1.4 is great for landscape and architecture photography.
The NOKTON 21mm F1.4's 12-bladed aperture produces well-defined 12-pointed sunstars. The aperture ring on the lens has detentes in 1/3 stops. A click-stop switching mechanism makes it possible to declick the aperture ring for video work.
The NOKTON 21mm F1.4 Aspherical uses a floating mechanism to maintain excellent image quality throughout the focusing range. Its aspherical elements minimize distortion and chromatic aberrations.
The M-mount version is specially designed for manual focusing coupled precisely with the camera's rangefinder system.

Sentiment Score 65%The Voigtlander 21mm F1.4 sets the standard in sharpness for a wideangle lens, controls CA well and while the bokeh has some shortcomings I would rate it as an overall positive as well. Good flare resistance and well defined sunstars also add to it's appeal as a landscape lens. The only real negative I could find is the very strong vignetting. Handling is best in class and the lens feels very solid.

Sentiment Score 72%Vignetting is very present at F1.4 and is reduced around F2.8 but is still there at all apertures. Moderate barrel distorsion that can require a small correction for architectural subjects CA are present wide open when facing the sun but quite small Resistance to flare is good but you can obtain some small purple halo when you face the sun and you look for flare. Coma correction at f 1.4 is average but well controlled at F 2.8 The color rendition is very good and pleasant The contrast is excellent The background blur is soft and pleasant for a wide angle, it become a little bit more nervous in the borders.

- Very good background blur

Sentiment Score 76%The Voigtlander Nokton is one of only two in-production 21mm F1.4 lenses. It can lock onto subjects at 9.8 inches (0.25m) Close focus isn't a strong point for most rangefinder lenses. A lens this wide and this bright with full-frame support is a rara avis.
