Voigtlander Ultron 40mm f/2 SL II

Comparison—40/2 Ultron vs Nikon 45/2.8P and Zeiss ZF 35/2 Distagon

This comparison examines the relative performance of the Voigtlander 40/2 Ultron to the Zeiss ZF 35/2 Distagon and the discontinued Nikon 45mm f/2.P pancake lens. Since reproduction size is not matched, the comparison subjectively assesses the overall image and corner areas.

Click the image at the top of the page to see a full-frame image at 50% actual pixels. You might want to compare it to the entire frame from the Zeiss ZF 35/2 Distagon. Both entire-frame images sharpened as follows: Unsharp Mask {10,50,0}, Smart Sharpen {20,0.3,0}.

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.
