Comparing Video Quality at 1080 HD

These comparisons came as a huge shock to me— some results simply look downright blurry to my eyes. One must wonder if the actual resolution is closer to DVD quality than HD quality!

All cameras were set to highest quality using AWB and auto exposure, which means that smaller apertures used a higher ISO. The videos were shot across the full aperture range; f/5.6 stills were captured from the paused video stream for this presentation. Examination of the videos showed that choice of aperture has no effect on the conclusions or relative performance between cameras..

Stills are matched closely in size, except that the D800 and D800E “full frame” examples are shown twice; once with the 1.09X inherent crop at the same camera position as the Canon 5D Mark III and D4 and again at a greater distance, size matched (and thus with a bit more depth of field).

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.
