Nikon 24-70/2.8E VR vs 24/1.8G: Snowy White Mountain Road

Shot on the 36-megapixel Nikon D810. No filters were used and lenses were shaded by hand to avoid direct sunlight on the front lens element.

This comparison is a classic in this way: if one looks at just a few areas, it is all too easy to come to erroneous conclusions on sharpness, and without the insights as to why. It is a reason to use very large crops for context, as is done here.

The test scene affords detail from very close range to far distance, with high contrast fine details over much of the frame. A dominant issue with any and all wide angle lenses is field curvature, whether prime lens or zoom, and this scene lends itself well to assessing field curvature.

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.
