Nikon D800

D800E AF-S Accuracy: Nikon 28/1.8G (Mosaic)

The Nikon D800 showed autofocus issues, so naturally another camera body is of interest to see if the same left/right inaccuracy and asymmetry issues apply.

Nikon AF-S 28mm f/1.8G test scene

This is an infinity-focus test. Infinity focus might or might not reflect accuracy at closer range.

The focus points fell on the central mosaic, with the left point on the left-most angel, and the right point on the right-most angel.

All shots at f/1.8.

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 28 megapixels filling up to 5K display, 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.
