Sharpness: 5DS R vs 5DS vs 5D Mark III (Zeiss Siemens Chart)
The crops on this page are from the Zeiss Siemens Star Test Chart.
To compare the Canon 5DS R vs Canon 5DS vs Canon 5D Mark III, all the cameras were resampled to various sizes, making the differences easy to see, particularly at the 12,000 pixel size, but the downscaling (for 5DS/R) are also useful. Brightness was matched precisely at center.
Sharpening was the usual approach, which greatly reduces any difference between the Canon 5DS R and 5D acutance for fine details.

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.
