These examples shot on the 50-megapixel Canon 5DS R.
Images shot at f/9 - f/13 have diffraction mitigating sharpening applied. Chromatic aberration has been corrected for most of these images.
Images that are focus stacked are so-marked. While stacking greatly improves total sharpness and thus allows observing the total lens performance near to far without the damaging effects of diffraction (from stopping down too far), there is a slight loss of micro contrast from the stacking process because pixels have to be stretched to compensate for the differing magnification at different focusing distances).

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.
