Noise should be compared for the same reproduction ratio; per pixel noise is an erroneous way to compare noise, since higher megapixels means less enlargement. Hence this page compares the Canon 5DS R noise to that of the Canon 5D Mark III by downsampling to the 5DM3 resolution.
Due to different mounting brackets (no custom bracket available for 5DS R as this was shot), the images are slightly different in perspective. They have been aligned at center, and a slight crop done.
Images processed with Iridient Developer 3.0.3 due to the Adobe Camera Raw camera profile bug which delivers incorrect results with the Canon 5DS R.
Same exposure for both cameras using Zeiss Otus 85mm f/1.4 APO-Planar @ f/9. RawDigger confirms a perfect exposure for both cameras.

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.
