Voigtlander 28/2.8 SL II
Nikon 28mm f/1.8G

Compared vs Nikon 28/2 AIS, Voigtlander Color Skopar 28/2.8 SL II (Cottonwood Canyon Fall Color)

The Nikon AF-S 28mm f/1.8G is compared here to two other lenses using the 36-megapixel Nikon D800E:

RAW conversion

The brightness for all lenses was matched precisely at f/5.6 (exposure compensation, push or pull). The other apertures for each lens were then match to the f/5.6 frame, again using exposure compensation. This facilitates assessment without perceptual traps.

The Voigtlander lens was a consistent 1/3 to 1/2 stop darker than the Nikon 28/1.8G at the same aperture on this and other comparisons, which means that its T-stop is notably lower. The Voigtlander 28/2.8 is likely closer to T/3.5 at f/2.8, with the Nikon 28/1.8G closer to T/2.8— quite a shutter speed difference when the light is marginal.

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.
