Sharpness: 5DS R vs 5D Mark III (Mosaic)
There are several ways to compare different-resolution cameras:
- Upsample both to some common, higher resolution—this simulates a very large print.
- Show the actual pixels from each camera—what does each actually deliver?
- Downsample the higher-res camera to the lower-res resolution—per pixel quality for the same image at the same resolution.
All three approaches have validity, but the first one is most demonstrative of the difference in resolution, and quite compelling here.
Examples shot with the Zeiss Otus 85mm f/1.4 APO-Planar at f/5.6. There is no better performance to be had. A lesser lens will show less advantage for the 5DS R.
The slight rotational change was unavoidable (mounting brackets on the 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.
