36MP Nikon D810
Nikon AF-S 28mm f/1.4E ED

Aperture Series: Burghers of Calais

This scene tests the Nikon 28mm f/1.4E at close range with off-center focus to see how well the lens performs at wider apertures in the mid zones.

Mosaic

Adobe Camera Raw 9.10.1.750. View ACR Settings. Camera Profile = Adobe Standard. No lens corrections used. Diffraction mitigating sharpening for f/9, f/13.

Focus was on the the right eye (left side) of the burgher.

Wide open sharpness and micro contrast from f/1.4 through f/2.8 are good, but lacking in the 'bite' that starts at f/4 and peaks at f/6.3. It’s not that it’s a bad performance at f/1.4 through f/2.8, it’s that it is so-so and that f/4 is very good but still not as good as I’d expect from the Zeiss Otus 28/1.4 at f/2 (and maybe f/1.4). Since a subject off-center in this position is a very good use of a lens compositionally at times, this is a bit disappointing, but it is also consistent with the mid-zone and outer-zone decline in performance seen with all the other comparison.

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.
