Autofocus Errors with Nikon D3x, D3s

The 12MP Nikon D3s also shows the same issues as seen here, so that shows that both an $8K and a $5K Nikon body can't focus the 35/1.4G properly, and rules out a camera body issue. I have also verified that the problem occurs at distance, and at 60/50/30/20/10 feet. Adding +10 fine focus adjustment to D3x gets it close, but further research shows that fine focus is not a solution.

These tests are with my December 2010 evaluation lens.

I had focus issues with the Nikon 24mm f/1.4G, so the first shot I took out my door with the 35mm f/1.4G was a quick but effective test of the 35/1.4G, shown below. Additional controlled tests show a very sharp lens but with consistent and horrendous autofocus error, as you can see for yourself from the examples on this page.

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.
