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.

Diglloyd DAP is DSLR-oriented, but also contains workflow and other topics. Much of the focus is on Canon and Nikon but also Pentax and Pentax medium format.

Special emphasis is placed on lens evaluation, focusing on Canon and Nikon and Sigma lenses, but with a few others like Rokinon/Samyang.

  • Make better images by learning how to get the best results right away.
  • Save money by choosing the right lens for your needs the first time, particularly some of the new Sigma Art lenses vs Nikon and Canon.
  • Workflow discusses image organization, raw conversion and post processing. Many examples show processing parameters for direct insight into how the image was converted.
  • Jaw-dropping image quality found nowhere else utilizing Retina-grade images up to full camera resolution, plus large crops [past 2 years or so].
  • Real world examples with insights found nowhere else. Make sharper images just by understanding lens behavior you won’t read about elsewhere.
  • Aperture series from wide open through stopped down, showing the full range of lens performance and bokeh.
  • Optical quality analysis of field curvature, focus shift, sharpness, flare, distortion, and performance in the field.
