Nikon 50mm f/1.2 AIS

Aperture Series: Cottonwood Stump (D800E)

This series shows the general imaging qualities of the Nikon 50mm f/1.2 AIS under pleasingly diffuse light at dusk.

The demanding 36-megapixel Nikon D800E is used here: a decades-old optical design on a high-resolution digital sensor is quite a challenge!

Cottonwood stump at DeChambeau Ranch

The westering mid-November sun hidden behind the Sierra Nevada casts a warm glow on this cottonwood tree stump at dusk. A slight contrast boost was made (Contrast +10 in ACR raw conversion).

The general bokeh qualities are of interest here; quite pleasant. There is a pleasing gentleness at wide apertures and at f/1.2 and f1.4 a moderately strong vignetting which draws attention towards the center. As well, that vignetting can be used as an inherent neutral density “filter” for too-bright corner details (though not in this scene).

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.
