Pattern Noise — Streaking and Banding (Picnic Table)
Here we have an about $6800 professional body that Canon claims to have exceptional pixel quality:
The images produced with the EOS-1D X camera's new sensor are so clean that files can easily be up-sized if necessary for even the most demanding high-resolution commercial applications.
Alrighty then. Can the 1D X make an image at ISO 100 that is free of pattern noise?
Test scene
Shown below is the scene as shot at ISO 100, 1/8000 second @ f/1.2. Aperture f/1.2 was chosen intentionally for a well-blurred background, to help reveal any pattern noise.

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.
