Nikon D810
Nikon AF-S 20mm f/1.8G ED

Aperture Series: Mt Conness Glacier Remnants (D810)

Shot with the 36-megapixel Nikon D810 at ISO 64. The 20/1.8G is compared to the Zeiss 21/2.8 Distagon on this scene in Guide to Zeiss.

The scene offers an ideal layout for studying the behavior of both lenses: a high contrast central area for focusing with an approaching foreground and distant background, long with good symmetry of subject matter (in terms of distance).

Mt Conness Glacier Remnants

This view up the heavily glaciated east valley of 12,649' Mt Conness shows the remnant glaciers abutting the escarpment leading to Mt Conness (eastern Yosemite).

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.
