Voigtlander Nokton 58mm f/1.4 SL

Bokeh—58/1.4 Nokton vs 58/1.2 NOCT-Nikkor

All examples are on the full-frame Nikon D3. Most images can be clicked to see a larger version and/or actual-pixels crops. Mouse-overs are also in place on this page for all of them.

The Nokton 58/1.4 and the Ultron 40/2 both have 9-bladed apertures that appear almost perfectly circular to the eye. No doubt this contributes to their pleasant out of focus rendering.

The comparisons on this page all match aperture eg f/1.4 for both the 58mm f/1.2 NOCT-Nikkor and the Nokton 58mm f/1.4. Because blur characteristics are most prominent at the widest aperture, f/1.4 is used for most of the examples. The NOCT-Nikkor can blur even a little more at f/1.2 of course.

Note that the actual focal lengths differ slightly, and thus the pairs of images don’t match precisely in size. In addition, vignetting is less at f/1.4 with the NOCT-Nikkor because it has been stopped down by 1/2 stop. The NOCT can be expected to have smoother image rendition by virtue of a more circular aperture as compared with the Nokton, which will be partially vignetted by the lens barrel wide open at f/1.4.
