Shootout vs Nikon D850: Yellow Tractor

This page looks at resolving power and overall visual impact and pixel quality of the Pentax K-1 Mark II with and without pixel shift versus the Nikon D850.

Images are shown at native sizes for both cameras, as well as at enlargements of 72 and 311 megapixels, along with crops shown from the 311MP size. Why show an enlargement of 311 megapixels? Because its width of 21600 pixels corresponds to 300 dpi with a 6-foot-wide print (1.83 meters wide). And because crops from that resolution are easy to view and see differences.

Quality and processing notes

JPEG saved near-lossless quality for the full camera resolution images for both cameras (7360 and 8256 sizes). Scaled sizes and respective crops at a quality that cannot be distinguished by eye.

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.
